Fix for TWL5030 Silicon Errata 27 & 28:
27 - VDD1, VDD2, may have glitches when their output value is updated.
28 - VDD1 and / or VDD2 DCDC clock may stop working when internal clock
is switched from internal to external.
Workaround requires the TWL DCDCs to use HFCLK instead of internal oscillator.
Also enable TWL watchdog before switching the osc to recover
if the VDD1/VDD2 stop working.
Fix is required for TWL5030 Silicon version less than or equal to ES1.1
Changes are done under the macro CONFIG_TWL5030_GLITCH_FIX,
since the IDCODE register on TWL5030 Si is not updated correctly.
Updated the TWL resource settings and volt, clock setuptime.
Changes taken from Nishanth Menons gaia glitch fix patch.

This patch has dependency on:
SmartReflex patch series from Thara.
Update TRITON power scripts from Lesly.
This patch series is based off Kevin's tree origin/pm branch.
This changes are tested on OMAP3430 SDP board with:
enable_off_mode
voltage_off_while_idle
sleep_while_idle (VDD1/VDD2 voltage scaling to 0v) enabled in cpuidle and suspned path.
Also tested for reboot and dvfs.
