commit 1e31927aa64545ee97a2a41db9984c9931afc50a upstream.
Recently kernelCI reported the board mt7622-rfb1 has a fail test with kernel: ERROR: did not start booting whose details could be seen at [1].
The cause is that UART0 can't output anything when it's missing a proper pin setup with current DTS, so the essential driver is always getting enabled to fix up the issue.
