Get rid of bogus CONFIG_SYS_BUS_HZ and CONFIG_SYS_CONFIG_BUS_CLK definitions
CONFIG_SYS_BUS_HZ has not really been used anywhere except to be redined as CONFIG_SYS_BUS_CLK; in addition, the mpc7448hpc2 had the bogus CONFIG_SYS_CONFIG_BUS_CLK setting which duplicated the funtionality. Change all this to use CONFIG_SYS_BUS_CLK consistently.
