spi: xilinx: Convert to let spi core validate bits_per_word

Browse source

Set bits_per_word_mask so spi core will reject transfers that attempt to use
an unsupported bits_per_word value.

spi_bitbang requires custom setup_transfer() to be defined if there is a
custom txrx_bufs(). Thus keep the empty xilinx_spi_setup_transfer() function
in the code.
