Get rid of bogus CONFIG_SYS_BUS_HZ and CONFIG_SYS_CONFIG_BUS_CLK definitions

Browse Source 
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.
