firmware: arm_scmi: Add qcom smc/hvc transport support
This change adds the support for SCMI message exchange on Qualcomm
virtual platforms.
The hypervisor associates an object-id also known as capability-id
with each smc/hvc doorbell object. The capability-id is used to
identify the doorbell from the VM's capability namespace, similar
to a file-descriptor.
The hypervisor, in addition to the function-id, expects the capability-id
to be passed in x1 register when SMC/HVC call is invoked.
The capability-id is allocated by the hypervisor on bootup and is stored in
the shmem region by the firmware before starting Linux.
