Remove mode awareness from PMIC voltage setting, current setting, and
enable/disable functions. Concepts such as regulator consumers do not
work well with multiple modes, so support for changing voltages or
disabling regulators in each mode has been removed.

PMIC regulator disable function was unconditionally disabling the PMIC
regulator when the disable API was called, which does not match the
expected behavior when using the onoff service. Fix this error.

Add support for setting the target mode for a PMIC regulator. Some
regulators support multiple modes, each with distinctive voltage and
current configuration data. This function allows the consumer to switch
the PMIC into a new mode. The PMIC can then be configured to use a new
set of voltages.

Move I2C register reads to regulator_read_register in regulator driver,
to enable better abstraction of regulator I2C reads

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.

The regulator-pmic node is a child of the I2C device. When this
was converted to i2c_dt_spec that was missed.
Also fixed a few minor formatting issues.

In order to bring consistency in-tree, migrate all drivers to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to #45388 for more details.

Remove unneeded NULL check in pmic init function. Not required as
device_is_ready() will handle NULL device structs.

Config struct in pmic regulator driver was being used as a non-constant
value when an array defined at compile time was cast to a struct used at
runtime. Move this pointer to the data struct in pmic driver.

This commit adds support for editing the voltage levels on the buck
regulators on the PCA9420 PMIC
Signed-off-by: Daniel DeGrasse <daniel.degrasse@nxp.com>
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.
