Add ams AS3722 entry for gpio/pincontrol and regulators

This patch still causes:

[ 0.726545] as3722-pinctrl as3722-pinctrl: pin gpio0 already
requested by as3722-pinctrl; cannot claim for as3722-regulator
[ 0.737681] as3722-pinctrl as3722-pinctrl: pin-0
(as3722-regulator) status -22
[ 0.744895] as3722-pinctrl as3722-pinctrl: could not request pin 0
(gpio0) from group gpio0 on device as3722-pinctrl
[ 0.755500] as3722-regulator as3722-regulator: Error applying
setting, reverse things back
This error is nothing related to the ams dt or driver. This came from
the framework from the driver/base for adding pinmux call before calling
any diver's probe.
OK, after reverting the problematic MFD commit (which I assume will
happen upstream too), I see no errors caused by this patch.

As such, I've applied the series to Tegra's for-3.14/dt branch.
Thanks for taking care.


Note that I couldn't verify if the pinctrl setup in patch 1/2 matched
the ChromeOS kernel, since the node order is different there, and the
property values don't use named constants there. I'll have to trust you.
I'll be annoyed if it turns out we need to churn the pinctrl
configuration in the future...

I referred the configuration from chrome branch. I assume that good amount of testing has already been done on this configuration.
I manually check all configuration and run chrome on this change which works properly. Did not see any abnormal behavior.
So if something missed then it is just human error which did not catch on 2 level of self review.

Again any change on this configuration can be expected based on new testing or bringung new modules.
