The series does below fixes to the omap3 low power code.
1. Use supported ARMv7 instructions instead of the legacy ones
2. Fix the MMU on sequence
3. Fix the cache flush scenario when only L1 lost.
4. Remove all un-necessary context save registers
5. Disable C-bit before cache clean
6. Use set_cr() exported API instead of custom one.
It's generated against mainline and tested with OMAP3630 ZOOM3.
1. Renetion and off-mode mode in suspend - ok.
2. Retention in idle - ok
