mtd: chips: reorganize Kconfig help on swapping 

The Kconfig help on "Flash cmd/query data swapping" still mentions
LART_ENDIAN_BYTE. That option used to be relevant for setting
CONFIG_MTD_CFI_LART_BIT_SWAP. That option and macro got both removed in
v2.4.11-pre4. So, although LART endianness sounds intriguing, that part
of the help text can be removed.

And, while we're touching this choice, move the help text up one level.
Currently it's available under the "NO" option, while it's relevant for
all three options.

Specific arrangements are possible with the BIG_ENDIAN_BYTE and
LITTLE_ENDIAN_BYTE, if the bytes are reversed.
If you have a LART, on which the data (and address) lines were
connected in a fashion which ensured that the nets were as short
as possible, resulting in a bit-shuffling which seems utterly
random to the untrained eye, you need the LART_ENDIAN_BYTE option.
Yes, there really exists something sicker than PDP-endian :)
