IFC IP clock is always a constant divisor of platform clock
pre-defined per SoC. Clock control register (CCR) used in
current implementation governs IFC IP output clock.
Update sys_info->freq_localbus to represent IFC input clock with
value constant divisor of platform clock.

This feature seems to be sometimes misunderstood. The intention is:
[1] Bring the slaves into the U-Boot proper image, not SPL (unless
you have a special reason to do otherwise).
[2] The operation must be done in a board (SoC) specific manner
since how to wake the slaves from the Boot ROM is SoC specific.
[3] The slaves must enter U-Boot proper after U-Boot relocates
itself because the "cpu-release-addr" property points to the
relocated memory area.
[2] is already explained in the help. We can make [1] even clearer
by mentioning "U-Boot proper" instead of "U-Boot". [3] is missing,
so I am adding it to the list. Instead, "before the master CPU
jumps to the kernel" is a matter of course, so removed.
