Arnd Bergmann 936fc53f3d 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().
