[PATCH v2] Revert "staging: mt7621-pinctrl: replace core_initcall_sync with builtin_platform_driver"

[Sergio Paracuellos]

That patch causes the network interface on the device to stop working.
device_initcall() is called much later than core_initcall_sync() and
that seem to be a problem. Revert it to get a correct behaviour.
