ARM: dts: msm: add PMS405 peripherals for QCS405

QCS405 uses PMS405 PMIC. Add PMS405 peripherals to QCS405
device tree.

Also add RPM managed regulator devices for QCS405 so that
the client requests made for these regulators are aggregated
by the RPM processor along with the requests from other
processors.

QCS405 rumi platform does not contain PMS405. Remove PMS405
peripherals and RPM managed regulator devices from QCS405
RUMI device tree and add stub regulator devices.
