[PATCH v4 2/9] dt-bindings: mfd: brcm,bcm59056: Add compatible for BCM59054

[Artur Weber <aweber.kernel@gmail.com>]

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

Changes in v4:
- Fix yamllint errors (missing unevaluatedProperties)
- Drop comment with regulator name list
- Use full schema paths for $reg
- Change description of regulator binding to mention BCM59054
  explicitly
- Drop quotes around vbus reg name
- Change "Power Management IC" to "Power Management Unit" to match
  official Broadcom naming

Note that I did not end up moving the regulator refs from
allOf compatible matches; I explained my reasoning in [1].

Changes in v3:
- Split regulator node into separate file
- Removed quotes around compatible
