Qualcomm driver updates for 6.2

The qcom,msm-id and qcom,board-id DeviceTree properties are documented,
to allow them to be used in configurations or devices requiring these
and the socinfo driver is updated to reuse the introduced identifiers.

The rpmh-rsc driver is extended to register for PM runtime notifications
from the CPU clusters, in order to submit sleep and wake votes the last
core in a cluster is being powered down.

A mechanism for keeping rpmhpd resources voted until sync_state is
introduced, this ensures that power-domains required during boot are
kept enabled. The rpmhpd power-domains for SDM670 are also added.

Support for the new QDU1000/QRU1000 platform is introduced in the rpmhpd
and socinfo drivers.

The APR driver gains missing error handling. QMI message descriptors in
the PDR driver are made const.

Support for the RPM found in SM6375 is added. The SPM driver gains
support for MSM8939 and MSM8976 platforms.

The stats and command-db drvers are marked as not having PM support.
