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.

This can easily derived from the PWRST flag instead of hardcoding
it this way. Also note that INACTIVE PD isn't supported in mainline
yet because of voltage-domain dependency planned changes.

All of the PD structures are manually coded. This whole file is
auto-generated and even these field generation needs to follow
that path.
Ok I need to check that. Any pointer on how to generate those?
The scripts needs to be updated to generate this additional information.
Will send you some pointer off the list.
