[PATCH] pinctrl/pinctrl-u300: remove unused variable i

[Devendra Naga]

the unused variable warning was thrown when compiled using the
gcc for ARM (arm-linux-gnueabihf-gcc) with u300_defconfig selected,

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- u300_defconfig

and then

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-

gives the following warn,

drivers/pinctrl/pinctrl-u300.c: In function ‘u300_pmx_remove’:
drivers/pinctrl/pinctrl-u300.c:1178:6: warning: unused variable ‘i’ [-Wunused-variable]

Incidentally I was working on this code and fixed the same issue,
but thanks anyway!
