mx53: Make PLL2 to be the parent of UART clock

Change the parent UART clock to be PLL2, so that U-boot can also boot
a Freescale 2.6.35 kernel for mx53.

FSL kernel and U-boot changed the UART parent from PLL3 to PLL2 to avoid
conflicts with IPU clocks, so that the video resolution can be changed
without affecting the UART clock.

On a 2.6.35 kernel the serial console is messed up after IPU driver is loaded
and this patch fixes this problem.

Tested on a mx53loco board booting a FSL kernel and also a mainline kernel.
