[PM-SR][PATCH 4/4] omap3: voltage: expose omap_change_voltscale_method

[Nishanth Menon <nm@ti.com>]

omap_change_voltscale_method is to be used by board files
to choose which mechanism they would prefer to do update
of voltage to thier PMIC. unless we expose it, they cant
use it.

This also fixes sparse warning:
arch/arm/mach-omap2/voltage.c:1046:6: warning: symbol 'omap_change_voltscale_method' was not declared. Should it be static?
