regulator: Updates for v5.5 Another fairly quiet release for the regulator API, some work all around including some core work but mostly in specialist or driver specific code: - Fix for powering off boot-on regulators. - Enhancements to the coupled regulator support introduced in the last release. - Conversion of a bunch of drivers to the fwnode API for GPIOs. - Mode support for DA9062. - New device support for Qualcomm PM1650, PM8004 and PM895 and Silergy SR83X. - Removal of obsolete AB8505 support.
