Subject: [PATCH 08/17] ARM: at91: unused variable in at91_pm_verify_clocks

The code using the variable 'i' in this function is conditional, so
we have to make the declaration conditional as well to avoid a harmless
warning.

Without this patch, building at91sam9263_defconfig results in:

/home/arnd/linux-arm/arch/arm/mach-at91/pm.c: In function 'at91_pm_verify_clocks':
/home/arnd/linux-arm/arch/arm/mach-at91/pm.c:137:6: warning: unused variable 'i' [-Wunused-variable]
