MSM8974PRO is commonly used for referring to Snapdragon 801, compared to
MSM8974 which is Snapdragon 800.

The Snapdragon 801 has three variants with different clock speeds, with
the -AA, -AB and -AC suffix.

2. Add limits to interrupts.
3. Add child nodes (bcm-voter, clock-controller, power-controller).

Add bindings for the AHB bus which exposes the SSC (Snapdragon Sensor Core)
block in the global address space. This bus (and the SSC block itself) is
present on certain qcom SoCs.

In typical configuration, this bus (as some of the clocks and registers
that we need to manipulate) is not accessible to Linux, and the resources
on this bus are indirectly accessed by communicating with a hexagon CPU
core residing in the SSC block. In this configuration, the hypervisor is
the one performing the bus initialization for the purposes of bringing
the hexagon CPU core out of reset.

However, it is possible to change the configuration, in which case this
driver will initialize the bus.

In combination with drivers for resources on the SSC bus, this driver can
aid in debugging, and for example with a TLMM driver can be used to
directly access SSC-dedicated GPIO pins, removing the need to commit
to a particular usecase during hw design.

Finally, until open firmware for the hexagon core is available, this
approach allows for using sensors hooked up to SSC-dedicated GPIO pins
on mainline Linux simply by utilizing the existing in-tree drivers for
these sensors.

To move the list iterator variable into the list_for_each_entry_*()
macro in the future it should be avoided to use the list iterator
variable after the loop body.

To *never* use the list iterator variable after the loop it was
concluded to use a separate iterator variable instead of a
found boolean [1].

This removes the need to use a found variable and simply checking if
the variable was set, can determine if the break/goto was hit.

   - Unroll string MMIO for encrypted SEV guests as the hypervisor

     takes the feature set of the fpstate buffer into account. The
     feature sets can differ between host and guest buffers. Guest
     buffers do not contain supervisor states. So far this was not an
     issue, but with enabling PASID it needs to be handled in the buffer
