- Add flash entries for Atmel AT25SF321, Spansion S28HL256T, S28HL02GT.
- Add support for vcc-supply regulators and their DT bindings.
- Drop mx25u25635f entry. The flash shares its ID with mx25u25645g and
both parts have an SFDP table. Removing their entry lets them be
driven by the generic SFDP-based driver.
