powerpc: ppc4xx: drop unused variable

Browse Source 
commit 0d36fe65f5
"powerpc: ppc4xx: use gpiochip data pointer"
made the mm_gc local variable in ppc4xx_gpio_set()
redundant, and when GCC treats warnings as errors this
happens:

arch/powerpc/sysdev/ppc4xx_gpio.c: In function 'ppc4xx_gpio_set':
arch/powerpc/sysdev/ppc4xx_gpio.c:93:26: error:
  unused variable 'mm_gc' [-Werror=unused-variable]
     struct of_mm_gpio_chip *mm_gc = to_of_mm_gpio_chip(gc);
                             ^
   cc1: all warnings being treated as errors
