The sysreset uclass has an option to provide the do_poweroff() function.
When that option is enabled, the AXP power drivers should not provide
their own definition.
For the AXP305, which is paired with 64-bit systems where TF-A provides
PSCI, there is another possible conflict with the PSCI firmware driver.
This driver can be enabled even if CONFIG_PSCI_RESET is disabled, so
make sure to use the right symbol in the condition.

As part of migrating to DM_GPIO and DM_PINCTRL, eventually we will
remove the asm/arch/gpio.h header. In preparation, clean up the various
files that include it.
Some files did not contain any GPIO code at all, so this header was
completely unused.
A few files contained only legacy platform-specific GPIO code for
setting up pin muxes. They were left unchanged, as that code will be
completely removed by the DM_PINCTRL migration.
The remaining files contain some combination of DM_GPIO and legacy GPIO
code. For those, switch to including asm/gpio.h (if it wasn't included
already). Right now, this header provides both sets of functions,
because ARCH_SUNXI selects GPIO_EXTRA_HEADER. This will still be the
right header to include once the DM_GPIO migration is complete and
GPIO_EXTRA_HEADER is no longer needed.

We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.
Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.
This requires quite a few header-file additions.

Fix typo in axp_set_dldo() so that it correctly uses AXP818_DLDO1_CTRL
register to configure the voltage instead of setting AXP818_ELDO1_CTRL
register which is obviously incorrect.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

Previously, AXP818 ALDO support was partially added to Kconfig, but
never enabled in the board file, nor properly set or configured in
Kconfig. The boards continue to work because the AXP818 is designed
to pair with the A83T/H8, and the default voltages match the reference
design's requirements.

AXP818 is rsb based PMIC and used on Allwinner A83T H8 Homlet dev board.
It's registers are different and calculating reg config is different than
that of earlier axp power ICs.
DCDC1, DCDC2, DCDC3 and DCDC5 is implemented at the moment.
all other voltages can be added subsequently.
