mfd: bcm2835-pm: Introduce SoC-specific type identifier
Power management blocks across the BCM2835 family share a common
base but require variant-specific handling. For instance, the
BCM2712 lacks ASB register space, yet it manages the power domain
for the V3D graphics block.
Add a hardware type identifier to the driver's private data. This
allows the driver to distinguish between SoC models and implement
custom quirks or features as needed.
