power: axp209: Limit inrush current for broken boards

Some boards feature a capacitance on LDO3's output that is too large,
causing inrush currents which as a result, shut down the AXP209. This
has been reported before, without knowing the actual cause.

A fix appeared to be done with
commit 0e6e34ac8dbb ("sunxi: Olimex A20 boards: Enable LDO3 and LDO4 regulators").

The description there is a bit misleading, the kernel does not hang
during AXP209 initialization, the PMIC shuts down, causing voltages to
drop and thus the whole system freezes.

While the AXP209 does have the ability to ramp up the voltage slowly, to
reduce these inrush currents, the voltage rate control (VRC) however is
not applicable when switching on the LDO3 output. Only when going from
an enabled lower voltage setting, to a higher voltage setting is the VRC
in effect.

To work around this problem, we set LDO3 to the lowest possible setting
of 0.7 V if it was not yet enabled, and then let the VRC (if enabled) do
its thing. It should be noted, that for some undocumented reason, there
is a short delay needed between setting the LDO3 voltage register and
enabling the power. One would expect that this delay ought to be just
after enabling the output power at 0.7 V, but this did not work.

This allows for the power to gradually rise up to the desired voltage,
instead of spiking up as fast as possible. Reason to have this can be
to reduce the inrush currents for example.

There are 3 slopes to choose from, the default, 'none' is a voltage rise
of 0.0167 V/uS, a 1.6 mV/uS and a 0.8 mV/uS voltage rise.

In ideal world (where vendors follow the recommended design guidelines)
this setting should not be enabled by default. Unless of course AXP209

Linux 4.20.0. Hence all board maintainers of am33xx based boards are
on the cc list.
The main purpose of this patch is to prevent further diverging of the
dts files from U-Boot and those from Linux. It aims to set the stage
for the synchronization of board specific dts files. Example: I'm the
maintainer of the PDU001 board: once this patch is applied successfully
I will make changes to the board specific dts file in Linux only and
then post a patch with a copy of this exact dts file to U-Boot. This
will make U-Boot and Linux remain in sync.
The stumbling block of https://patchwork.ozlabs.org/patch/943627 was
removed by the patch https://patchwork.ozlabs.org/patch/962428 from
Lokesh Vutla (many thanks!). This omap-serial driver allows using the
Linux am33xx.dtsi file in U-Boot.
Other changes to dts and dtsi files made by this patch are mainly to
prevent _new_ warnings during the build process. Especially the warning
at pinmux@800 stating 'unnecessary #address-cells/#size-cells without
"ranges" or child "reg"' was not removed. This warning is a good example
showing the benefit of the synchronization: if it needs to be fixed it
will be fixed in Linux and ported back to U-Boot.
Buildman reports all 46 am33xx SoC based boards to build fine, with
warnings of course. Nevertheless this patch should be tested thoroughly
on as many boards as possible to prevent any collateral damage.

In commit e5e06b65ad65 ("clk: Allow clock defaults to be set also
during re-reloc state") the earlier guard against setting clock
defaults in pre-reloc state was removed.  While it is easy to filter
'assigned-clocks' properties for SPL using CONFIG_OF_SPL_REMOVE_PROPS,
no such mechanism exists for the pre-reloc stage of the full U-Boot.

With the default defconfig for the RK3399-Q7 (which filter the
'assigned-clocks' property for the DTS used by SPL anyway), this
caused a pause during startup of the full U-Boot stage that lasted for
almost 10s (due to the CPU not having been clocked up yet).

This reintroduces the guard from commit f4fcba5c5baa ("clk: Allow
clock defaults to be set also during re-reloc state") and extends it
to only apply outside of a TPL/SPL build: i.e. clk_set_defaults will
now run in pre-reloc state for SPL, but only after reloc for the full
U-Boot.
