firmware: arm_scmi: Augment SMC/HVC to allow optional parameters

Browse source

This change adds support for passing shmem channel address as parameters
in smc/hvc call. The address is split into 4KB-page and offset.
This is useful when multiple scmi instances are using same smc-id
and firmware needs to distinguish among the instances.
