Fixes gcc '-Wunused-but-set-variable' warning:
drivers/mmc/host/alcor.c: In function 'alcor_data_set_dma':
drivers/mmc/host/alcor.c:124:12: warning:
variable 'len' set but not used [-Wunused-but-set-variable]
drivers/mmc/host/alcor.c:648:15: warning:
variable 'clock_out' set but not used [-Wunused-but-set-variable]
It never used since introduction in commit 2a9a4742e825 ("mmc: add new Alcor
