spi: npcm: Remove set but not used variable 'val'

Browse Source 
Fixes gcc '-Wunused-but-set-variable' warning:

drivers/spi/spi-npcm-pspi.c: In function npcm_pspi_handler:
drivers/spi/spi-npcm-pspi.c:296:6: warning: variable val set but not used [-Wunused-but-set-variable]

It is not used since commit 2a22f1b30c ("spi:
npcm: add NPCM PSPI controller driver")
