Currently MPC85xx and MPC86xx boards just calculate the localbus frequency and print it out, but don't save it. This changes where its calculated and stored to be more consistent with the CPU, CCB, TB, and DDR frequencies and the MPC83xx localbus clock. The localbus frequency is added to sysinfo and calculated when sysinfo is set up, in cpu/mpc8[56]xx/speed.c, the same as the other frequencies are. get_clocks() copies the frequency into the global data, as the other frequencies are, into a new field that is only enabled for MPC85xx and MPC86xx. checkcpu() in cpu/mpc8[56]xx/cpu.c will print out the local bus frequency from sysinfo, like the other frequencies, instead of calculating it on the spot.
