util: improve iteflash help output

Some lines in 'itflash --help' output got quite long. This patch
modifies the code so that the output looks as follows:

vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
Usage: ./build/host/util/iteflash [-d] [-v <VID>] [-p <PID>] \
      [-c <ccd|ftdi>] [-i <1|2>] [-s <serial>] [-u] \
      [-e] [-r <file>] [-W <0|1|false|true>] [-w <file>] \
      [-R base[:size]]
--d[ebug] : output debug traces
--e[rase] : erase all the flash content
-c, --i2c-interface <ccd|ftdi> : I2C interface to use
--i[interface] <1> : FTDI interface: A=1, B=2, ...
--p[roduct] <0x1234> : USB product ID
[-R|--range base[:size]] - allow to read or write just a slice of the file,
    starting at <base>:<size> bytes, or til the end of the file if <size>
    is not specified, expressed in hex
--r[ead] <file> : read the flash content and write it into <file>
--s[erial] <serialname> : USB serial string
--u[nprotect] : remove flash write protect
--v[endor] <0x1234> : USB vendor ID
-W, --send-waveform <0|1|false|true> : Send the special waveform?
    Default is true. Set to false if ITE direct firmware update
    mode has already been enabled.
--w[rite] <file> : read <file> and write it to flash
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

BRANCH=none
BUG=none
TEST=ran 'make BOARD=host utils' and verified that iteflash --help
     output matches the above.
