[POWERPC] Fix mpc52xx serial driver to work for arch/ppc again

From: Grant Likely <redacted>

The mpc52xx_uart_of_enumerate() function was added when adding 52xx
support to arch/powerpc, but it must not be called for arch/ppc.

Please include for .20; without this patch you cannot build an arch/ppc
kernel for the lite52xx.
