Two different processors on a SOC need to switch memory ownership
during load/unload. To enable this, second level memory map table
need to be updated, which is done by secure layer.
This patch adds the interface for making secure monitor call for
memory ownership switching request.

In order to aid post-mortem debugging the Qualcomm platforms provide a
"memory download mode", where the boot loader will provide an interface
for custom tools to "download" the content of RAM to a host machine.
The mode is triggered by writing a magic value somewhere in RAM, that is
read in the boot code path after a warm-restart. Two mechanism for
setting this magic value are supported in modern platforms; a direct SCM
call to enable the mode or through a secure io write of a magic value.
In order for a normal reboot not to trigger "download mode" the magic
must be cleared during a clean reboot.
Download mode has to be enabled by including qcom_scm.download_mode=1 on
the command line.

This patch adds a set remote state SCM API. This will be used by the
Venus and GPU subsystems to set state on the remote processors.
This work was based on two patch sets by Jordan Crouse and Stanimir
Varbanov.

This patch adds a Qualcomm specific quirk to the arm_smccc_smc call.
On Qualcomm ARM64 platforms, the SMC call can return before it has
completed. If this occurs, the call can be restarted, but it requires
using the returned session ID value from the interrupted SMC call.
The quirk stores off the session ID from the interrupted call in the
quirk structure so that it can be used by the caller.
This patch folds in a fix given by Sricharan R:
