staging: sm750fb: Remove set but not used variable 'actual_mx_clk'

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

drivers/staging/sm750fb/ddk750_chip.c: In function set_chip_clock:
drivers/staging/sm750fb/ddk750_chip.c:59:15: warning: variable actual_mx_clk set but not used [-Wunused-but-set-variable]

It is not used since commit f0977109a577 ("staging:
sm750fb: lower case to fix camelcase checkpatch warning")
