OMAP3+: VP: move voltage scale function pointer into struct voltagedomain
Function pointer used for actual voltage scaling (e.g. VP force update or VC bypass) is moved from omap_vdd_info into struct voltagedomain, resulting in renames s/vdd->volt_scale/voltdm->scale/ No functional changes. Signed-off-by: Kevin Hilman <khilman@ti.com>
