powerpc/5xxx: Add common mpc5xxx_get_bus_frequency() function
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. Signed-off-by: Wolfgang Denk <wd@denx.de> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
