pci: brcmstb: Support different variants using a cfg struct
The Linux kernel driver already had support for multiple hardware
variants when the bcm2712 was added (see e.g. linux commit
10dbedad3c818 which is the last in a longer set of changes). This
patch brings in this required infrastructure and adds a
differentiation between 2711 and 2712 register layouts on top.
