[PM-SR][PATCH 3/4] omap3: voltage: make required variables static

[Nishanth Menon <nm@ti.com>]

debugfs voltage_dir - used only by voltage layer and no reason for
others to add data to it, so make it static.  omap3_vp_offs,
volt_mod have no business being exposed as global. make them static

This fixes sparse warnings:
arch/arm/mach-omap2/voltage.c:42:15: warning: symbol 'voltage_dir' was not declared. Should it be static?
arch/arm/mach-omap2/voltage.c:49:5: warning: symbol 'volt_mod' was not declared. Should it be static?
arch/arm/mach-omap2/voltage.c:130:27: warning: symbol 'omap3_vp_offs' was not declared. Should it be static?
