Convert devicetree bindings for the Broadcom BCM59056 PMU MFD from
TXT to YAML format. This patch does not change any functionality;
the bindings remain the same.
The bindings have been split into two parts: the MFD binding and
a separate binding for the regulator node, to simplify the addition
of other models later (which have different regulators).

The BCM59054 MFD is fairly similar to the BCM59056, and will use
the same driver. Add compatible and specify the allowed regulator
nodes.

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.

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.

Changes in v9:
- Put params to dev_dbg print on one line
Changes in v8:
- Change PMU ID print from dev_info to dev_dbg
- Unwrap some lines and let them go up to 100 chars
- Drop comment above bcm590xx_parse_version (keep the comments inside
the function, they make it a bit more clear what's happening since
it's doing two separate things)
Changes in v7:
- Return -ENODEV on PMU ID mismatch
- Drop "Check your DT compatible" from ID mismatch error message
Changes in v6:
- Adapt to PMUID being passed as device type value
- Rename rev_dig and rev_ana to rev_digital and rev_analog
- Rewrite commit message
Changes in v5:
- Add REG_ prefix to register offset constant names
Changes in v4:
- Added this commit

Instead of calling dev_err() and returning PTR_ERR(...) separately, use
a single "return dev_err_probe" statement.

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.

Previously, the driver used the BCM590XX prefix for register data
specific to the BCM59056. As we will be introducing other regulators
to this driver as well, make the BCM59056-specific values use the
BCM59056 prefix.

The BCM59056 and BCM59054 are very similar in terms of regulators. Add
the register definitions for the BCM59054 and enable support for it in
the driver.

Changes in v6:
- dev_type -> pmu_id conversion, rev_ana -> rev_analog rename
Changes in v5:
- Adapt to regmap type enum being moved/value names being renamed
- Adapt to rename of bcm590xx_reg_info to bcm590xx_reg_data
Changes in v4:
- Lock MICLDO at 1.8v to match vendor kernel behavior
- Set different voltage table for VSR based on PMU revision
- Fix incorrect table being used for LVLDO1
- Add missing newline to "unknown device type" error message
Changes in v3:
- Adapt to regulator info being moved to tables
