Subject: [PATCH v2] spi: spi.h: add missing kernel-doc for @last_cs_index_mask

kernel-doc complains about last_cs_index_mask not described, so add its
description.

spi.h:778: warning: Function parameter or struct member 'last_cs_index_mask' not described in 'spi_controller'

Fixes: 4d8ff6b0991d ("spi: Add multi-cs memories support in SPI core")
