When we call regmap_init, the regmap is associated with the device
supplied and can be queried with dev_get_regmap. This is more natural
than expecting cell drivers to cast dev->parent->priv. Do it.

We now have a regulator driver for the stpmic1, so no need to replace
the stpmic1 v3v3 regulator with a fixed regulator.
This reverts commit 911978ec7b7c05c6456e714edf1082785ab2191c.

Linux regulator drivers like the pfuze and the incoming stpmic make use
of of_regulator_match to parse regulator init data from the device tree.
Port the function over from Linux v5.3, so drivers depending on it can
follow.
As we have no use in barebox for power saving and suspend states, these
This commit imports the Linux v5.3 state of the driver. This allows us
to regulate at least the v3v3 voltage rail used by the DK1 and DK2
Ethernet PHY and SD-Card. Eventually, this driver should be used by the
USB host driver to supply the vbus voltage as well.

For testing regulator drivers, it can be handy to enable/disable them
from the shell prompt. Extend the regulator command to support this.

This node has so far been unused and is a remnant from when the stm32mp

In preparation for teaching the regulator command how to enable and
disable regulators, move the regulator command implementation to the
regulator core, so the internal interfaces for iterating through the
list of available regulators can be more easily used.

The incoming stpmic1 regulator driver makes use of these helpers
internally. Thus port them out of Linux v5.3.

For more usability, translate CPU_ON error codes into the error
descriptions found in the PSCI Platform Design Document[1].

We'll probably be using compressed DTBs for all new boards as well, thus
move the ARM_USE_COMPRESSED_DTB, so it's always selected for STM32MP.

There's already an option to use when debugging PSCI. Instead of
requiring users to #define DEBUG 1 as well, have the smc command be
usable when CONFIG_ARM_PSCI_DEBUG, not DEBUG is defined.

ARM TF-A reports compatibility with PSCI v1.1 since v1.5. Upstream
ARM TF-A support for STM32MP was introduced with v1.6.
It's thus safe to assume that the STM32MP barebox will never have to
interact with a secure monitor implementing PSCI v0.1.
Overwrite the psci device tree compatible to
The smc command has a help defined, but unused. Wire it in, so
help smc and smc -invalidoption work as expected.
While at it, remove the unimplemented -z option. It's unneeded,
because -c turns off the CPU after starting it again already.
Also it seems it's not implementable without
In cases where firmware provides PSCI >0.1, it may be prudent to use it as
backend for reset and poweroff. This driver accomplishes this.
