regulator: qcom_spmi: add support for HT_P150

Browse source 
HT_P150 is a LDO PMOS regulator based on LV P150 using HFS430 layout
found in PMP8074 and PMS405 PMIC-s.

Both PMP8074 and PMS405 define the programmable range as 1.616V to 3.304V
but the actual MAX output voltage depends on the exact LDO in each of
the PMIC-s.

It has a max current of 150mA, voltage step of 8mV.
