Changes in v2:
* Rebased to next-20230420
Apparently i.MX6UL was missed in commit 0822f933735c ("clk: imx6: retain
early UART clocks during kernel init"). But as commit 379c9a24cc23 ("clk:
imx: Fix reparenting of UARTs not associated with stdout") changes the
calling signature it's not warranting a Fixes for the old commit.
