of: align RESERVEDMEM_OF_DECLARE function callbacks to other callbacks

All the parameters for RESERVEDMEM_OF_DECLARE function callbacks are
members of struct reserved_mem, so just pass the struct ptr to callback
functions so the function callback is more in line with other OF match
table callbacks.
