spi: omap-100k: Remove set but not used variable 'dataH'

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

drivers/spi/spi-omap-100k.c: In function spi100k_read_data:
drivers/spi/spi-omap-100k.c:140:6: warning: variable dataH set but not used [-Wunused-but-set-variable]

It is not used since commit 35c9049b ("Add OMAP spi100k driver")
