Add support for the ROHM BD73800 PMIC and compatibles.

The ROHM BD73800 is a power management IC which integrates 8 BUCKs and 4
LDOs. There is also an ADC and operation amplifier intended for current
/ temperature measurement and accumulation. RTC and 32.768 kHz clock
gate are also included. The PMIC can be customized via OTP and it has
options for operating as a main PMIC in multi-PMIC installation. Some
of the pins can also be used for GPO or GPI (including interrupt support).

There are also ROHM BD71851 and BD71885 PMICs out there. These are, from
the SW-perspective, similar to the BD73800. There is only some different
default values and OTP settings. The driver should be able to handle them
just fine.

Revision history:

v2 => v3:
- Rebased on v7.3-rc1.
- gpio: Use gpio-regmap as was suggested by Linus W.
More accurate change-log in individual patches.

v1 => v2:
- Rebased on regulator/for-7.3 as it carries dependency:
f29a8bf6fde1 ("regulator: dt-bindings: ROHM PMIC state-machine voltages")
- dt-bindings: Various fixes, split generic stuff to own files.
- gpio: Styling, return -ENODEV if no GPIOs found
- MFD: Styling
- regulator: Simplify dt-reading
More accurate change-log in individual patches.

I assume there will be one more revision?


Hi Lee,

I thought everything was acked and good to go?
