Subject: [PATCH] [ARM] davinci: gpio: eliminate unused variable warnings

Since commit 5093aec872e5be7a55d8dd2b639e8a3818dc19db
"arm: davinci: Cleanup irq chip code", 
the variable 'mask' and 'g' are not being used in gpio_irq_type.

This patch eliminate below unused variable warnings:

  CC      arch/arm/mach-davinci/gpio.o
arch/arm/mach-davinci/gpio.c: In function 'gpio_irq_type':
arch/arm/mach-davinci/gpio.c:234: warning: unused variable 'mask'
arch/arm/mach-davinci/gpio.c:233: warning: unused variable 'g'
