eeprom, eepromer: remove the tools

These tools are deprecated for 6 years now because we have better
alternatives. They are not built by default. I think it is time we can
remove them.

-	It works only on true i2c bus adapters.
-	See README.eeprom for details.
-	This program is deprecated, please use eeprog instead.
-
-Use eepromer for large eeproms with two-byte addresses:

-	It works only on true i2c bus adapters.
-	See README.eepromer for details.
-	This program is deprecated, please use eeprog instead.
-
-Use eeprog for either small or large eeproms.
-	This program was moved to a separate subdirectory.
-	Use the -16 switch for large eeproms.
-	It works on both i2c and smbus bus adapters.

-It has several options:
-
-	-d devicenode
-
-		set this to the device-node of the i2c-bus
-		you want to use like /dev/i2c-0.
-		Use /dev/i2c-1 for the second bus, i2c-2 for the third...
-
-		The default /dev/i2c-0 should work most of the time.
-
-	-a address
-
-		set this to the device-address of your
-		eeprom. For a 24C16 the address is hardcoded to
-		0x50, which is -you guessed it- the default.
-
-		For a 24C08 and smaller types you can choose which
-		addresses they occupy by forcing the address-pins
-		of the chip to High or Low so here the address may differ.
-
-	-p number_of_pages
-
-		set this to the number of pages you want to read
-		from or write to the eeprom. The 24C16 maps it's
-		pages to consecutive addresses on the i2c-bus so
-		we will try to read 256 bytes from every i2c
-		address between 'address' (inclusive) and
-		'address + number_of_pages' (exclusive)...
-
-		A 24C16 has 8 pages so that's the default for this
-		parameter.
-
-	-f filename
-
-		read data from this file (when writing to eeprom) or
-		write data to this file (when reading from eeprom).
-
-		When reading a file that's smaller than the
-		eeprom's storage size we will pad the eeprom
-		with zeroes.
-
-		If no file is given we will just read the
-		eeprom (while in read-mode) and test it's presence
-		this way. In write-mode we will just write zeroes
-		to the eeprom.
-
-	-w	When '-w' is present we will *write* to the eeprom.
-		If you do not specify '-w' we will read the contents
-		of the eeprom.
-
-	-y	This flag will suppress the warning when you write to the
-		eeprom. You will not be required to enter 'yes' so be careful
-		when using this switch!
-
-
-I wrote that program to clear a 24C16 eeprom that sit's in my crappy
-satellite receiver because sometimes its Z80 processor likes to
-write garbage to it and then crash....
-
-No further testing besides writing a long series of "The quick brown
-fox jumps over the lazy dog!" and reading it back has been done so
-of course this comes without any warranty.

-Simple program for storing data to I2C EEPROM.
-
-This program is deprecated, please use eeprog instead.
-
-!!!!!!!!!!!!!!!!!!!!!!!!Warning!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
-
-The EEPROM must be a large EEPROM which uses a 2-byte address
-field (24C32 or larger). It will NOT WORK on small EEPROMs
-(24C01 - 24C16) such as those used on SDRAM DIMMs.
-
-Tested only on 24C256.
-
-!!!!!!!!!!!!!!!!!!!!!!!!Warning!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
-
-This program is intended for use on eeproms using external busses such as 
-i2c-pport.
-Do not use this on your SDRAM DIMM EEPROMS, it won't work!!!!!!!!!
-Doing so will render your SDRAM USELESS  and leave your system UNBOOTABLE!!!
-
-!!!!!!!!!!!!!!!!!!!!!!!!Warning!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
-
-Options:
-	-r  read
-	-w  write
-	-e  erase
-	-p  print "super block of EEPROM" (date and size stored data)

-.TH eeprom "8" "Jul 2013" "i2c-tools" "System Administration"
-.SH NAME
-eeprom \- reads and writes 24Cxx EEPROMs connected to I2C serial bus
-.SH SYNOPSIS
-.B eeprom
-[-d dev] [-a addr] [-p pgs] [-w] [-y] [-f file]
-.SH DESCRIPTION
-.B eeprom
-can be used for reading from / writing to I2C EEPROMs like the popular
-24C16, 24C08, 24C04, etc.
-In contrast to
-.B eeprommer
-which supports 24C256-type EEPROMs,
-this tool works with 1-byte addresses!
-.SH NOTES
-Don't forget to load your i2c chipset and the i2c-dev drivers.
-.P
-Pages/addresses:
-    EEPROMs with more than 256 bytes appear as if they
-    were several EEPROMs with consecutive addresses on the bus
-    so we might as well address several separate EEPROMs with
-    increasing addresses
-.SH PARAMETERS
-.TP
-.B dev
-device (default /dev/i2c-0)
-.TP
-.B addr
-base address of EEPROM (default 0xA0)
-.TP
-.B pgs
-number of pages to read (default 8)
-.TP
-.B \-w
-write to EEPROM (default is reading!)
-.TP
-.B \-y
-suppress warning when writing (default is to warn!)
-.TP
-.B \-f file
-copy EEPROM contents to/from file (default for read is test only; for write is all zeros)
-.SH SEE ALSO

-.BR eepromer (8)

-.SH NAME
-eepromer \- reads and writes 24Cxx EEPROMs connected to I2C serial bus
-.SH SYNOPSIS
-.B eepromer
-[-r|-w|-e|-p] -f <device> <i2c-addr>
-.SH DESCRIPTION
-The EEPROM must be a large EEPROM which uses a 2-byte address
-field (24C32 or larger). It will NOT WORK on small EEPROMs
-(24C01 - 24C16) such as those used on SDRAM DIMMs.
-.SH NOTES
-Don't forget to load your i2c chipset and the i2c-dev drivers.
-.P
-Tested only on 24C256.
