ARM: OMAP3/4: cpuidle: fix sparse and checkpatch warnings 

Fix the following sparse warnings in the OMAP3/4 CPUIdle code:

arch/arm/mach-omap2/cpuidle34xx.c:272:1: warning: symbol 'omap3_idle_dev' was not declared. Should it be static?
arch/arm/mach-omap2/cpuidle34xx.c:274:23: warning: symbol 'omap3_idle_driver' was not declared. Should it be static?
arch/arm/mach-omap2/cpuidle44xx.c:164:1: warning: symbol 'omap4_idle_dev' was not declared. Should it be static?
arch/arm/mach-omap2/cpuidle44xx.c:166:23: warning: symbol 'omap4_idle_driver' was not declared. Should it be static?

Also fix the following checkpatch warnings:

WARNING: please, no space before tabs
#44: FILE: arch/arm/mach-omap2/cpuidle34xx.c:105:
+^I.name = ^I"omap3_idle",$

WARNING: please, no space before tabs
#45: FILE: arch/arm/mach-omap2/cpuidle34xx.c:106:
+^I.owner = ^ITHIS_MODULE,$

ERROR: code indent should use tabs where possible
#211: FILE: arch/arm/mach-omap2/cpuidle44xx.c:74:
+                        /* C2 - CPU0 OFF + CPU1 OFF + MPU CSWR */$
