[PATCH v3 0/5] BCM59056 PMU regulator support

The BCM59056 is a multi-function power management unit used with the
BCM281xx family of SoCs. This series adds an MFD and voltage regulator
driver to support the BCM59056. The bcm28155-ap DT support is updated
to enable use of regulators on the otg and sdhci peripherals.

Changes since v2:
- Move to mfd_add_devices() approach, eliminating representation
of the regulator block as a hardware subdevice. Regulators are
listed in the PMU binding and referenced via the parent device
of_node by the regulator driver.
- Allow mfd driver to build as module
- Remove regulator constraints from the .dtsi include only the
board-specific constraints in the board .dts.

Changes since v1:
- renamed to bcm590xx to accomodate future family parts
- remove use of subsys_initcall
- fix BCM590XX_MAX_REGISTER value
- remove unused chip id in mfd of/i2c matching
- switch to of_platform_populate() in mfd
- update binding to single document with regulators as optional
properties in the regulator subdevice IP description
- remove unused regulator get/set mode ops
- remove unneeded regulator NULL constraint check
- regulators property is optional, allow the driver to probe
when it is missing
- move of_node presence check into bcm590xx_parse_dt_reg_data()
