firmware: meson-sm: rework meson_sm_init to use module_platform_driver_probe
Commit 3aa0582fdb82 ("of: platform: populate /firmware/ node from
of_platform_default_populate_init()") takes care of populating
all the devices under the /firmware/ node in of_platform_default_populate_init()
This patch reworks meson_sm_init to use module_platform_driver_probe as
the platform device is populated.
