Add SW support for MAXIM Semiconductor's Power Management
IC (PMIC) MAX77620/MAX20024. This PMIC supports DC-DC/LDOS, GPIOs,
RTC, watchdog, clocks etc.

This series add respective driver for each of sub-modules.

Changes from V1:
DT DOC:
- Added units in some of properties.
- Change the boolean property to tristate type and detail some of
properties.

RTC:
- Rename the file to rtc-max77xxx.c and make the generic implementation.
- Direct regmap apis are used for the register access.
- Decouped from max77620 driver.
- Taken care of cleanup comments form V1 version.

MFD:
- Code cleanups per review from V1.
- Move register access APIs from header to c file.
- Remove some of non required variable, remove duplication in error message
and simplify some of function implementation.

GPIO:
- Use the gpiochip_add_data and get the chip data from core APIs.
- Cleanups based on comment received on mfd/rtc.
- Avoid duplication on error message.

Pinctrl:
- Cleanup code based on comment received on mfd/rtc.
- Avoid duplication on error message.

Regulators:
- Cleanup code based on comment received on mfd/rtc.
- Avoid duplication on error message.
- Taken care of review comment from Mark.

Changes from V2:
- Run coccicheck and checkpatch in strict mode for the alignment.
- Drop RTC driver and its i2c client registartion.
- Refactor Regulator driver to use core API for DT parsing.

Changes from V3:
- Change all sys initcall to module driver.
- change the max77620_read argument to unisgned int from u8.

Changes from V4:
- Provide more details in the dt binding doc.
- Take care of fps nodes.
- Split the submodule's DT binding doc on respective folder.
- Drop the battery charger and low battery binding and related code as
it need to go on power driver.
