Subject: [PATCH 3/5] regulator: add regulators driver for Marvell 88PM886 PMIC

Support the LDO and buck regulators of the Marvell 88PM886 PMIC.

Signed-off-by: Karel Balej <balejk@...fyz.cz>

Notes:
    v1:
    - Add remaining regulators.
    - Clean up includes.
    - Address Mark's feedback:
      - Use dedicated regmap config.
    RFC v4:
    - Initialize regulators regmap in the regulators driver.
    - Register all regulators at once.
    - Drop regulator IDs.
    - Add missing '\n' to dev_err_probe message.
    - Fix includes.
    - Add ID table.
    RFC v3:
    - Do not have a variable for each regulator -- define them all in the
      pm886_regulators array.
    - Use new regulators regmap index name.
    - Use dev_err_probe.
    RFC v2:
    - Drop of_compatible and related code.
    - Drop unused include.
    - Remove some abstraction: use only one regmap for all regulators and
      only mention 88PM886 in Kconfig description.
    - Reword commit message.
