Move all command code into its own directory

There are a lot of unrelated files in common, including all of the commands.
Moving them into their own directory makes them easier to find and is more
logical.

Some commands include non-command code, such as cmd_scsi.c. This should be
sorted out at some point so that the function can be enabled with or without
the associated command.

Unfortunately, with m68k I get this error:

m68k:  +   M5329AFEE
+arch/m68k/cpu/mcf532x/start.o: In function `_start':
+arch/m68k/cpu/mcf532x/start.S:159:(.text+0x452): relocation truncated to fit: R_68K_PC16 against symbol `board_init_f' defined in .text.board_init_f section in common/built-in.o

I hope someone can shed some light on what this means. I hope it isn't
depending on the position of code in the image.

- * I2C Functions similar to the standard memory functions.
- *
- * There are several parameters in many of the commands that bear further
- * explanations:
- *
- * {i2c_chip} is the I2C chip address (the first byte sent on the bus).
- *   Each I2C chip on the bus has a unique address.  On the I2C data bus,
- *   the address is the upper seven bits and the LSB is the "read/write"
- *   bit.  Note that the {i2c_chip} address specified on the command
- *   line is not shifted up: e.g. a typical EEPROM memory chip may have
- *   an I2C address of 0x50, but the data put on the bus will be 0xA0
- *   for write and 0xA1 for read.  This "non shifted" address notation
- *   matches at least half of the data sheets :-/.
- *
- * {addr} is the address (or offset) within the chip.  Small memory
- *   chips have 8 bit addresses.  Large memory chips have 16 bit
- *   addresses.  Other memory chips have 9, 10, or 11 bit addresses.
- *   Many non-memory chips have multiple registers and {addr} is used
- *   as the register index.  Some non-memory chips have only one register
- *   and therefore don't need any {addr} parameter.
- *
- *   The default {addr} parameter is one byte (.1) which works well for
- *   memories and registers with 8 bits of address space.
- *
- *   You can specify the length of the {addr} field with the optional .0,
- *   .1, or .2 modifier (similar to the .b, .w, .l modifier).  If you are
- *   manipulating a single register device which doesn't use an address
- *   field, use "0.0" for the address and the ".0" length field will
- *   suppress the address in the I2C data stream.  This also works for
- *   successive reads using the I2C auto-incrementing memory pointer.
- *
- *   If you are manipulating a large memory with 2-byte addresses, use
- *   the .2 address modifier, e.g. 210.2 addresses location 528 (decimal).
- *
- *   Then there are the unfortunate memory chips that spill the most
- *   significant 1, 2, or 3 bits of address into the chip address byte.
- *   This effectively makes one chip (logically) look like 2, 4, or
- *   8 chips.  This is handled (awkwardly) by #defining
- *   CONFIG_SYS_I2C_EEPROM_ADDR_OVERFLOW and using the .1 modifier on the
- *   {addr} field (since .1 is the default, it doesn't actually have to
- *   be specified).  Examples: given a memory chip at I2C chip address
- *   0x50, the following would happen...
- *     i2c md 50 0 10   display 16 bytes starting at 0x000
- *                      On the bus: <S> A0 00 <E> <S> A1 <rd> ... <rd>
- *     i2c md 50 100 10 display 16 bytes starting at 0x100
- *                      On the bus: <S> A2 00 <E> <S> A3 <rd> ... <rd>
- *     i2c md 50 210 10 display 16 bytes starting at 0x210
- *                      On the bus: <S> A4 10 <E> <S> A5 <rd> ... <rd>
- *   This is awfully ugly.  It would be nice if someone would think up
- *   a better way of handling this.
