Zilin Guan da4b44c42f soc: microchip: mpfs: Fix memory leak in mpfs_sys_controller_probe() ...

[ Upstream commit 5a741f8cc6 ]

In mpfs_sys_controller_probe(), if of_get_mtd_device_by_node() fails,
the function returns immediately without freeing the allocated memory
for sys_controller, leading to a memory leak.

Fix this by jumping to the out_free label to ensure the memory is
properly freed.

Also, consolidate the error handling for the mbox_request_channel()
failure case to use the same label.
