firmware: arm_scmi: Simplify chan_available transport operation
SCMI transport operation .chan_available determines in a transport
specific way if an SCMI channel is still available and to be configured.
Such information is derived by analyzing bits of device node in a
transport specific way, all it needs is a device node to operate up on,
not necessarily a full blown device.
Simplify the helper to receive in input a reference to a device_node
instead of a device carrying a pointer to such device_node.
