ARM: OMAP5: Add the WakeupGen IP updates
OMAP4 and OMAP5 share same WakeupGen IP with below few udpates on OMAP5.
- Additional 32 interrupt support is added w.r.t OMAP4 design.
- The AUX CORE boot registers are now made accessible from non-secure SW.
- SAR offset are changed and PTMSYNC* registers are removed from SAR.
Patch updates the WakeupGen code accordingly.
