Update the data from the measurements performed at HW and SW levels.

Cf. http://www.omappedia.org/wiki/Power_Management_Device_Latencies_Measurement
for a detailed explanation on where are the numbers magically coming from.

ToDo:
- Measure the wake-up latencies for all power domains for OMAP3
- Correct some numbers when sys_clkreq and sys_offmode are supported
