Now that this functionality is modeled using the device tree and
regulator uclass, the named GPIO is not referenced anywhere. Remove it.

Most AXP PMICs feature a "startup source" register, which keeps
information about how the PMIC started operation. Bit 0 in there means
it has been started by "plugging in the power cable".
Define a symbol in each PMIC's header file to be able to use that
register and bit later on.

A single DM-based driver should be able to support some feature for
several PMIC variants where the interface is the same. For example,
all PMIC variants use the same register bit to trigger poweroff.
However, currently only definitions for a single PMIC are available at
a time. This requires drivers to use #ifdefs and different indentifiers
for each variant they support.
Let's simplify this by making register definitions for all variants
available from the header. Then no preprocessor conditions are needed;
the driver can use the register definition from any variant that
supports the relevant feature.
An exception is the GPIO-related definitions, which do not use unique
identifiers. So for now, keep them like before. They will be cleaned up
along with the GPIO driver.

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.

The A80 uses the AXP809 as its primary PMIC.
