spi: spi-meson-spicc: Remove set but never used variable 'data' from meson_spicc_reset_fifo() 

Looks like it hasn't ever been checked.

Fixes the following W=1 kernel build warning(s):

 drivers/spi/spi-meson-spicc.c: In function ‘meson_spicc_reset_fifo’:
 drivers/spi/spi-meson-spicc.c:365:6: warning: variable ‘data’ set but not used [-Wunused-but-set-variable]
 365 | u32 data;
 | ^~~~
