make some hardcoded PL010/PL011 stuff configurable

Hi,

attached is a small patch against u-boot-1.1.1 that replaces some hardcoded stuff for the PL010/PL011 Amba PrimeCells with configuration variables. It also (hopefully) fixes the wrong default value of CONFIG_CMD_DFL in README.

Regards,
Andreas
