clk: imx6q: fix uart earlycon unwork
[ Upstream commit 283f1b9a0401859c53fdd6483ab66f1c4fadaea5 ]
The earlycon depends on the bootloader setup UART clocks being retained.
There're actually two uart clocks (ipg, per) on MX6QDL,
but the 'Fixes' commit change to register only one which means
another clock may be disabled during booting phase
and result in the earlycon unwork.
Cc: stable@vger.kernel.org # v5.10+
