[ARM] 3426/1: ARM: OMAP: 1/8 Update clock framework

Patch from Tony Lindgren

Update OMAP clock framework from linux-omap tree.
The highlights of the patch are:

- Add support for omap730 clocks by Andrzej Zaborowski
- Fix compile warnings by Dirk Behme
- Add support for using dev id by Tony Lindgren and Komal Shah
- Move memory timings and PRCM into separate files by Tony Lindgren
