OMAP3+: voltage: rename scale and reset functions using voltdm_ prefix
Rename voltage scaling related functions to use voltdm_ prefix intead of omap_voltage_, and cleanup kerneldoc comments in the process. s/omap_voltage_scale_vdd/voltdm_scale/ s/omap_voltage_reset/voltdm_reset/ Also, in voltdm_reset() s/target_uvdc/target_volt/ to be consistent with naming throughout the file. No functional changes. Signed-off-by: Kevin Hilman <khilman@ti.com>
