[PATCH v2 7/7] OMAP: PM CONSTRAINTS: add power domains wake-up latency figures

[Jean Pihet]

Figures are added to the power domains structs.

Note: the figures are preliminary figures. More accurate measurements
are needed. Also the conditions of measurements shall be investigated
and described.

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