[PATCH v6 0/2] Add qcom smc/hvc transport support

[Nikunj Kela]

This change augments smc transport to include support for Qualcomm virtual
platforms by passing a parameter(capability-id) in the hypervisor call to
identify which doorbell to assert. This parameter is dynamically generated
at runtime on the device and insuitable to pass via the devicetree.

The capability-id is stored by firmware in the shmem region.

This has been tested on ARM64 virtual Qualcomm platform.

---
v6 -> use unsigned long for cap-id

v5 -> changed compatible, removed polling support patch,
      make use of smc-id binding for function-id

v4 -> port the changes into smc.c

v3 -> fix the compilation error reported by the test bot,
      add support for polling based instances

v2 -> use allOf construct in dtb schema,
      remove wrappers from mutexes,
      use architecture independent channel layout

v1 -> original patches
