The "id" member of the bcm590xx struct is unused and will be confusing
once we add an actual PMU ID storage value. Drop it; a replacement
will be introduced in a future commit.

Instead of filling in the regulator description programatically,
store the data in a struct. This will make it a bit nicer to
introduce support for other BCM590xx chips besides the BCM59056.
To do this, add a new struct type, bcm590xx_reg_data, to store
all of the necessary information. Drop the old IS_LDO, IS_GPLDO...
macros in favor of the "type" field in this struct. Adapt the
old bcm590xx_reg struct to the new types.

The BCM590xx PMUs have two I2C registers for reading the PMU ID
and revision. The revision is useful for subdevice drivers, since
different revisions may have slight differences in behavior (for
example - BCM59054 has different regulator configurations for
revision A0 and A1).
Check the PMU ID register and make sure it matches the DT compatible.
Fetch the digital and analog revision from the PMUREV register
so that it can be used in subdevice drivers.
Also add some known revision values to bcm590xx.h, for convenience
when writing subdevice drivers.

The BCM59054 is another chip from the BCM590xx line of PMUs, commonly
used on devices with the BCM21664/BCM23550 chipsets.
Prepare the BCM590xx driver for supporting other devices by adding the
PMUID register values for supported chip types and store them in the
MFD data struct as "pmu_id". (These will be checked against the actual
PMUID register values in a later commit.)
Then, add a DT compatible for the BCM59054, and provide the PMU ID as
OF match data.

BCM590xx utilizes a secondary I2C slave address to access additional
register space. Add support for the secondary address space by
instantiating a dummy I2C device with the appropriate secondary
I2C slave address. Also expose a secondary regmap register space so
that MFD drivers can access this secondary i2c slave address space.

Add a driver for the BCM590xx PMU multi-function devices. The driver
initially supports regmap initialization and instantiation of the
voltage regulator device function of the PMU.
