[PATCH 5/8] OMAP: PM CONSTRAINTS: add an enum for the classes of constraint

[jean.pihet at newoldbits.com]

From: Jean Pihet <j-pihet at ti.com>

Defined values in the enum:
- OMAP_PM_CONSTRAINT_WKUP_LAT
- OMAP_PM_CONSTRAINT_THROUGHPUT

More classes can be added later if needed.

Tested on OMAP3 Beagleboard in RET/OFF using wake-up latency constraints
on MPU, CORE and PER.
