regulator: ab8500: add initialization of vsmps regulators
Add initialization of Vsmps 1 2 and 3 regulators.
Also update vsmps1 voltage level and high-power/low-power control through
sysclk-request. Vpll high-power/low-power control through sysclk-request is
updated as well.
Please note that all vsmps3 related registers that is
AB8500_VSMPS3SEL1
AB8500_VSMPS3SEL2
AB8500_VSMPS3SEL3
AB8500_VSMPS3REGU
are PRCMU register and not supposed to be updated directly. Please remove them
once soc-settings is fully mature.
