[00/11] AB8500 charging fixes

Message

This is a first round of AB8500 charging patches for v5.18.

This fixes some minor and major bugs - they aren't tagged for
fixes or stable since the charging code is still default
disabled on the platform (Ux500) for a good reason
(it never worked properly).

We drop the custom charger sysfs ABI that we do not use anyway.

The thermal zone we are looking up is defined in a separate
DTS patch that will be merged through ARM SoC. The prerequisite
changes to the hwmon NTC driver were merged for v5.17 already.

Once this is agreed and merged I will follow this up with a
more important series with 6 patches that adds the
Samsung static battery data and actually makes charging
work on these platforms.
