[PATCH 1/1] ARM: OMAP: Kill warning in CPUIDLE code with !CONFIG_SMP

[PATCH 1/1] ARM: OMAP: Kill warning in CPUIDLE code with !CONFIG_SMP

[Mugunthan V N]

From: Santosh Shilimkar <santosh.shilimkar@ti.com>

for non SMP build, NR_CPUS is 1 and hence the code complains with below
warnings.

arch/arm/mach-omap2/cpuidle44xx.c:207:8: warning: array subscript is above array bounds [-Warray-bounds]
arch/arm/mach-omap2/cpuidle44xx.c:212:11: warning: array subscript is above array bounds [-Warray-bounds]

Kill it by making array size fixed.
