firmware: arm_scmi: Drop checking for shmem property in parent node
The scmi protocol core driver checks for the channel availability before evaluating the shmem property. If the individual protocols don't have separate channel assigned to them, the channel alloted for the BASE protocol is reused automatically. Therefore there is no need to check for the shmem property in the parent node if it is absent in the child protocol node.
