ARM: OMAP2+: voltage: Remove some unused functions
Removes some functions that are not used anywhere: omap_change_voltscale_method() voltdm_add_pwrdm() voltdm_for_each() voltdm_for_each_pwrdm() And remove define VOLTSCALE_VPFORCEUPDATE and VOLTSCALE_VCBYPASS This was partially found by using a static code analysis program called cppcheck.
