pinctrl: as3722: convert PINCTRL_AS3722 from bool to tristate
The Kconfig currently controlling compilation of this code is:
config PINCTRL_AS3722
bool "Pinctrl and GPIO driver for ams AS3722 PMIC"
...meaning that it currently is not being built as a module by anyone.
During an audit for non-modular drivers using modular infrastructure
this driver showed up.
But rather than demodularize it, Laxman indicated that it would be
prefereable to instead convert the driver option to tristate.
This does that, and confirms that it will compile and modpost as
such. However, since I do not have the hardware to confirm that
no new runtime issues exist when modular, that remains untested.
