Qualcomm driver updates for v5.15

Browse source 
This fixes the "shared memory state machine" (SMSM) interrupt logic to
 avoid missing transitions happening while the interrupts are masked.
 
 SM6115 support is added to smd-rpm and rpmpd.
 
 The Qualcomm SCM firmware driver is once again made possible to compile
 and load as a kernel module.
 
 An out-of-bounds error related to the cooling devices of the AOSS driver
 is corrected. The binding is converted to YAML and a generic compatible
 is introduced to reduce the driver churn.
 
 The GENI wrapper gains a helper function used in I2C and SPI for
 switching the serial engine hardware to use the wrapper's DMA-engine.
 
 Lastly it contains a number of cleanups and smaller fixes for rpmhpd,
 socinfo, CPR, mdt_loader and the GENI DT binding.

Qualcomm Always-On Subsystem side channel binding
This binding describes the hardware component responsible for side channel
requests to the always-on subsystem (AOSS), used for certain power management
requests that is not handled by the standard RPMh interface. Each client in the
SoC has it's own block of message RAM and IRQ for communication with the AOSS.
The protocol used to communicate in the message RAM is known as Qualcomm
Messaging Protocol (QMP)
The AOSS side channel exposes control over a set of resources, used to control
a set of debug related clocks and to affect the low power state of resources
related to the secondary subsystems. These resources are exposed as a set of
power-domains.
- compatible:
Usage: required
Value type: <string>
Definition: must be one of:
"qcom,sc7180-aoss-qmp"
"qcom,sc7280-aoss-qmp"
"qcom,sdm845-aoss-qmp"
"qcom,sm8150-aoss-qmp"
"qcom,sm8250-aoss-qmp"
"qcom,sm8350-aoss-qmp"
- reg:
Usage: required
Value type: <prop-encoded-array>
Definition: the base address and size of the message RAM for this
client's communication with the AOSS
- interrupts:
Usage: required
Value type: <prop-encoded-array>
Definition: should specify the AOSS message IRQ for this client
- mboxes:
Usage: required
Value type: <prop-encoded-array>
Definition: reference to the mailbox representing the outgoing doorbell
in APCS for this client, as described in mailbox/mailbox.txt
- #clock-cells:
Usage: optional
Value type: <u32>
Definition: must be 0
The single clock represents the QDSS clock.
- #power-domain-cells:
Usage: optional
Value type: <u32>
Definition: must be 1
The provided power-domains are:
CDSP state (0), LPASS state (1), modem state (2), SLPI
state (3), SPSS state (4) and Venus state (5).
= SUBNODES
The AOSS side channel also provides the controls for three cooling devices,
these are expressed as subnodes of the QMP node. The name of the node is used
to identify the resource and must therefor be "cx", "mx" or "ebi".
- #cooling-cells:
Usage: optional
Value type: <u32>
Definition: must be 2
= EXAMPLE
The following example represents the AOSS side-channel message RAM and the
mechanism exposing the power-domains, as found in SDM845.
aoss_qmp: qmp@c300000 {
compatible = "qcom,sdm845-aoss-qmp";
reg = <0x0c300000 0x100000>;
