Cheng Ming Lin 0758f7ef40 spi: Add check for 8-bit transfer with 8 IO mode support ...

commit 710505212e upstream.

The current SPI framework does not verify if the SPI device supports
8 IO mode when doing an 8-bit transfer. This patch adds a check to
ensure that if the transfer tx_nbits or rx_nbits is 8, the SPI mode must
support 8 IO. If not, an error is returned, preventing undefined behavior.

Fixes: d6a711a898 ("spi: Fix OCTAL mode support")
