dt-bindings: firmware: arm,scmi: support for parameter in smc/hvc call

Browse source

Currently, smc/hvc calls are made with smc-id only. The parameters are
all set to zeros. This change defines a new compatible string that can
be used to pass shmem address(4KB-page, offset) as two parameters in
SMC/HVC doorbell.

This is useful when multiple scmi instances are used with common smc-id.
