mfd: bcm590xx: Add support for multiple device types + BCM59054 compatible
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.
