regulator: qcom_spmi: Add support for LDO_510 and FTSMPS
Add support for LDO_510 and FTSMPS3 regulators, all belonging to register
layout HFSMPS. This is done in preparation for adding support for the
PM6125 PMIC.
For FTSMPS3 and LDO_510, only IDLE and NORMAL modes are selectable (no
FAST).
The inspiration for the magic constants was taken from [1]
