S5L8702: Move I/O addresses and bit masks from clocking driver to SoC definitions, reuse existing definitions
No difference in the produced binaries for ipod6g (normal and bootloader) This is a part of the large iPod Nano 3G and iPod Nano 4G support patch. Change-Id: Ib79c5539a317aae350d661ab23c181471ee38abb
