Qualcomm driver updates for v5.16

This drops the use of power-domains for exposing the load_state from the
QMP driver to clients, to avoid issues related to system suspend.

SMP2P becomes wakeup capable, to allow dying remoteprocs to wake up
Linux from suspend to perform recovery.

It adds RPM power-domain support for SM6350 and MSM8953 and base RPM
support for MSM8953 and QCM2290.

It adds support for MSM8996, SDM630 and SDM660 in the SPM driver, which
will enable the introduction of proper voltage scaling of the CPU
subsystem.

Support for releasing secondary CPUs on MSM8226 is introduced.

The Asynchronous Packet Router (APR) driver is extended to support the
new Generic Packet Router (GPR) variant, which is used to communicate
with the firmware in the new AudioReach audio driver.

Lastly it transitions a number of drivers to safer string functions, as
well as switching things to use devm_platform_ioremap_resource().
