mailbox: arm_mhuv2: Convert channel translation to fw_xlate()

Browse Source 
The MHUv2 channel translation callback only uses the mailbox specifier
arguments and does not depend on any OF-specific data from struct
of_phandle_args.

Switch to the generic fw_xlate() callback and use struct
fwnode_reference_args instead.

This aligns the driver with the mailbox framework's fwnode based channel
lookup support while preserving existing DT based operation.
