As part of bringing the master branch back in to next, we need to allow
for all of these changes to exist here.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

Remove <common.h> from this driver directory and when needed
add missing include files directly.

This adds support for reading the battery-backed memory present on these
RTCs. This modifies the read/write methods to access the RAM instead of
raw register offsets. No one was using these in-tree, so we should be
fine changing them.

We use the "standard" address space window to access the RAM. The
extension RAM address register has some reserved bits, but we write the
whole thing for simplicity (as these bits default to 0).

This is a basic driver for the ultra-low-power Abracon AB x80x series
of RTC chips. It supports in particular, the supersets AB0805 and AB1805.
It allows reading and writing the time, and enables the supercapacitor or
battery charger.
