iPod Classic: s5l8702 clocking rewrite+documentation

Browse source 
This is a rewrite of the clocking section, the resulting system
frequencies are the same as the current git version.

This pàtch uses fixed FClk and just one register is written to switch
all system frequencies, it needs less steps than the current git
version to reach the desired frequency, so it is faster and safer.
Includes functions to step-up/down over a table of predefined set of
frequencies.

The major difference is that Vcore is decreased from 1050 to 1000 mV.

See clocking-s5l8702.h for more information.
