Peng Fan 3ee1408eeb firmware: scmi: Validate device tree node before setup channel

SCMI base protocol device does not have a device tree, it should use and
need to use the agent base channel.

For scmi_base.[x], there is no real device tree node for it. ofnode_null() is
assigned as the device tree node for scmi base protocol device:
commit 7eb4eb541c ("firmware: scmi: install base protocol to SCMI agent")

However with recent update in commit 0535e46d55
("scripts/dtc: Update to upstream version v1.7.2-35-g52f07dcca47c"),
SPL panic in fdt_check_node_offset_()->fdt_next_tag(), because offset is -1
and SPL_OF_LIBFDT_ASSUME_MASK is 0xFF.

So add a check in x_get_channel() to validate the protocol devices'
ofnode.
