This adds APSS based ADSP PIL driver for QCOM SoCs.
Added initial support for SDM845 with ADSP bootup and
shutdown operation handled from Application Processor
SubSystem(APSS).

Changes since v1:
- Used APIs from qcom_q6v5.c
- Use clock, reset and regmap driver APIs instead of
directly writing into the LPASS registers.
- Created new file for non PAS ADSP PIL instead of extending
existing ADSP PIL driver.
- cleanups as suggested by Bjorn and Rob.

This should be a separate patch.
Ok. Will separate it in next spin.

Didn't Bjorn say to drop the 'apss' part?
Yes, he had asked to rename compatible string for existing PIL driver
as "qcom,platform-subsystem-pas"
and non-pas pil driver as "qcom,platform-subsystem-pil". I wanted to get
confirmation from Bjorn whether
we should rename the filename too.
@Bjorn, can you please suggest filename and compatible strings for the
two drivers.
