ppc4xx: Delete unused definitions for SDR0_DDRCFG from ppc4xx.h

The definitions of bits in SDR_CFG are incorrect, and not used within
U-Boot.  Therefore, they can be removed.

The naming of the sdr_ddrdl/sdr_cfg registers do not follow conventions,
and are unused, so they can be removed too.

A definition for SDR0_DDRCFG is added.
