firmware: arm_scmi: imx: Discover MISC board info from the system manager
The i.MX SCMI MISC protocol can report board information from the
System Manager (SM), including a board name and board-specific
attributes. Query this during protocol initialization.
If the firmware does not implement BOARD_INFO, handle -EOPNOTSUPP
gracefully and continue.

firmware: arm_scmi: imx: Support retrieving MISC protocol configuration info
The MISC protocol can provide System Manager (SM) configuration
information, including platform identifiers and board-specific
attributes. Add support to retrieve this information during protocol
initialization.
If the firmware does not implement the CFG_INFO command, handle
-EOPNOTSUPP gracefully and continue without failing init.
