Import all Linux properties, so that we can maximize compatiblity with
upstream bindings.

Following Linux regulator.yaml, regulator-name is a common property for
all regulators.

DTS property attributes are (by default) not required.
Explicitly specifying `required: false` is redundant.
Perhaps a warning to that effect would be useful.

The "pmic" driver was in reality a driver for NXP PCA9420 PMIC. There's
no "universal PMIC". While the driver may work for other NXP PMICs, it
is clearly not generic for other vendors PMIC.

Add support for regulator-boot-on to PMIC driver. Many PMIC devices will
be enabled at boot, so this property allows the regulator framework
to correctly track their state.

Add mode selection properties for regulator-pmic compatible. These
mode selection properties will be used with regulators that support
multiple modes, with each mode enabling specific voltage and current
limits.

Refactor binding to use root PMIC IC, so that properties can be shared
between regulator devices. Each individual regulator output is still
created as an individual device, since the regulator API aligns with
these devices better than the PMIC IC itself.

All in tree device drivers use some form of DEVICE_DT_GET
so we no longer need to require label properties.

This commit adds a generic i2c regulator driver, and enables the NXP
PCA9420 PMIC IC using this driver. The regulator driver also exposes an
additional API in include/drivers/regulator/consumer.h, which allows
drivers to implement support for adjusting voltage levels and current
limits, if their device supports it.

This provides structure for the regulator device hierarchy and a
driver for GPIO-controlled regulators along with its binding.

This PR follows Linux in defining devicetree content for generic
voltage and current regulators, and an initial driver API for
controlling them.
A regulator itself may depend on a power source, so it needs to
support the properties that enable that power source.
