spi: ppc4xx: Drop write-only variable

Browse source 
[ Upstream commit b3aa619a8b4706f35cb62f780c14e68796b37f3f ]

Since commit 24778be20f ("spi: convert drivers to use
bits_per_word_mask") the bits_per_word variable is only written to. The
check that was there before isn't needed any more as the spi core
ensures that only 8 bit transfers are used, so the variable can go away
together with all assignments to it.

Fixes: 24778be20f ("spi: convert drivers to use bits_per_word_mask")
