Use CONFIG_$(PHASE_)DM_REGULATOR_PFUZE100 as the build condition for
pfuze100 regulator driver.
Add Kconfig option for SPL_DM_REGULATOR_PFUZE100.
To avoid break current platforms, set the Kconfig default value same
as PMIC_PFUZE100.

Add a new regulator driver for MT6359P and similar PMIC chips.
The MT6359P is a eco version for MT6359 regulator. For the MT8391
platform, we use the MT6359P (MT6365) as the main PMIC. The MT6359 and
MT6359P have different register maps. Therefore, on the MT8391 platform,
we only provide support for the MT6359P. If support for the MT6359 PMIC
it can be added later.

The devm alloc functions that we have may follow the Linux kernel model
where allocations are (almost always) automatically free()'d. However,
quite often we don't enable, in full U-Boot, the tracking and free()'ing
functionality. This in turn leads to memory leaks because the driver
author expects that since the functions have the same name as in the
Linux Kernel they have the same behavior. In turn we then get
functionally correct commits such as commit 00e1fed93c8c ("firmware:
ti_sci: Fix memory leaks in devm_ti_sci_get_of_resource") that manually
add these calls. Rather than manually tracking allocations and
implementing free()s, rework things so that we follow expectations by
enabling the DEVRES functionality (outside of xPL phases).
This turns DEVRES from a prompted symbol to a symbol that must be
select'd, and we now remove our non-managed alloc/free functions from
outside of xPL builds.

SPL_DM_PWM option simply doesn't exist. Moreover, drivers/pwm is only
included by drivers/Makefile for non-xPL stages so making
SPL_REGULATOR_PWM properly build for SPL/xPL is more involved than just
adding an SPL_DM_PWM option.
Reading the original commit (ddc824f89aa8 ("power: regulator: Allow PWM
regulator to be omitted from SPL."), the intent seemingly wasn't to
allow building support in XPL but rather to allow removing it which is
done by using $(PHASE_) ($(SPL_) at that time) in the Makefile. If
anyone needs that, let them figure out what they need to do without
misleading potential users of this symbol by simply removing it.

In order to enable and build with SPL_REGULATOR_PWM we need to have both
SPL_DM_REGULATOR and SPL_DM_PWM enabled. Build-wise, we can have SPL
have PWM regulator support without enabling it in U-Boot itself so drop

This driver handles most voltage regulators found in X-Powers AXP PMICs.
It is based on, and intended to replace, the regulator driver in TF-A.
AXP PMIC regulators can be divided into 6 categories:
- Switches without voltage control => fully supported.
- Single linear range => fully supported.
- Two linear ranges, "step" and "2 * step" => fully supported.
- Two linear ranges, "step" and "5 * step" => only the first range is
supported. No boards are known to use the second range.
- Non-linear voltage values => fully supported.
- LDOs shared with GPIO pins => not supported.

power/regulator will not be built if just CONFIG_SPL_DM_REGULATOR is
enabled. It needs CONFIG_SPL_POWER_SUPPORT to be enabled as well.
For example, if we just need a GPIO regulator in SPL:
CONFIG_DM_REGULATOR=y
CONFIG_SPL_DM_REGULATOR=y
CONFIG_DM_REGULATOR_GPIO=y
CONFIG_SPL_DM_REGULATOR_GPIO=y
Will not suffice, since the entire regulator build for SPL depends on
CONFIG_SPL_POWER_SUPPORT. Elaborate that information in the Kconfig
dependency.

BD71837 and BD71847 is PMIC intended for powering single-core,
dual-core, and quad-core SoC’s such as NXP-i.MX 8M. BD71847
is used for example on NXP imx8mm EVK.
Add regulator driver for ROHM BD71837 and BD71847 PMICs.
BD71837 contains 8 bucks and 7 LDOS. BD71847 is reduced
version containing 6 bucks and 6 LDOs. Voltages for DVS
bucks (1-4 on BD71837, 1 and 2 on BD71847) can be adjusted
when regulators are enabled. For other bucks and LDOs we may
have over- or undershooting if voltage is adjusted when
regulator is enabled. Thus this is prevented by default.
BD718x7 has a quirk which may leave power output disabled
after reset if enable/disable state was controlled by SW.
Thus the SW control is only allowed for BD71837 bucks
3 and 4 by default. The impact of this limitation must be
evaluated board-by board and restrictions may need to be
modified. (Linux driver get's these limitations from DT and we
may want to implement same on u-Boot driver).

This adds a driver for the FAN53555 family of regulators and wraps it
in a PMIC implementation.
While these devices support a 'normal' and 'suspend' mode (controlled
via an external pin) to switch between two programmable voltages, this
incarnation of the driver assumes that the device is always operating
in 'normal' mode.
Only setting/reading the programmed voltage is supported at this time
and the following device functionality remains unsupported:
- switching the selected voltage (via a GPIO)
- disabling the voltage output via software-control
This matches the functionality of the Linux driver.
Tested on a RK3399-Q7 (with 'option 5' devices): setting voltages from
the U-Boot shell and verifying output voltages on the board.
