powerpc/5xxx: Add common mpc5xxx_get_bus_frequency() function

Browse Source 
So far, MPC512x used mpc512x_find_ips_freq() to get the bus frequency,
while MPC52xx used mpc52xx_find_ipb_freq().  Despite the different
clock names (IPS vs. IPB) the code was identical.

Use common code for both processor families.
