asus-wmi: try to guess the right DSTS methods
This is tricky, new WMI aware notebooks seems to use
0x53545344 while Eee PCs are using 0x53544344. But there
is no way to know if there is an Eee PC in that wild that is
using 0x53545344 or a notebook using 0x53544344. So the
driver try to guess the available DSTS method ... But most Eee PCs
never return 0xFFFFFFFE when a method is not available, they return
0 instead (and that's useless).
So, first, try 0x53544344 then 0x53545344. We will find
a better way when we got more data.

The downside of this is that mfd drivers need to be modified whenever

Linux's driver model better. It's also simpler.
This also converts cs5535-mfd/olpc-xo1 from the old API. cs5535-mfd

regulator: add set_voltage_time_sel infrastructure
This makes it possible to set the stabilization time for voltage
regulators in the same manner as enable_time(). The interface
only supports regulators that implements fixed selectors.

regulator: initialization for ab8500 regulators
The regulators on the AB8500 have a lot of custom
hardware control settings pertaining to 8 external
signals, settings which are board-specific and need
be provided from the platform at startup.
Initialization added for regulators Vana, VextSupply1,
VextSupply2, VextSupply3, Vaux1, Vaux2, Vaux3, VTVout,
Vintcore12, Vaudio, Vdmic, Vamic1, Vamic2, VrefDDR.

Regulator: add suspend-finish API for regulator core.
The regulator core had suspend-prepare that turns off the regulators
when entering a system-wide suspend. However, it did not have
suspend-finish that pairs with suspend-prepare and the regulator core
has assumed that the regulator devices and their drivers support
autonomous recover at resume.
This patch adds regulator_suspend_finish that pairs with the
previously-existed regulator_suspend_prepare. The function
regulator_suspend_finish turns on the regulators that have always_on set
or positive use_count so that we can reset the regulator states
appropriately at resume.
In regulator_suspend_finish, if has_full_constraints, it disables
unnecessary regulators.
