clk: imx6q: fix uart earlycon unwork 



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.
