v2:
- Add vendor-prefixes to DT binding definition header files.
Changes compared to the BSP:
- Add "-clk" suffix to clock node names,
- Rename "pmu_a76" node to "pmu-a76",
- Drop bogus CPU masks from GICv3 PPI interrupt specifiers,
- Drop hscif0 dmas and dma-names placeholder,
- Add missing hypervisor virtual timer IRQ to timer node.
