Merge tag 'mvebu-soc-4.5-1' of git://git.infradead.org/linux-mvebu into next/multiplatform

Merge "mvebu soc for 4.5 (part 1)" from Gregory CLEMENT:

- orion5x/mv78xx0 multiplatform conversion
- legacy dove PMU support conversion

* tag 'mvebu-soc-4.5-1' of git://git.infradead.org/linux-mvebu:
  ARM: dove: convert legacy dove to PMU support
  soc: dove: add legacy support to PMU driver
  ARM: orion5x: multiplatform support
  ARM: orion5x: clean up mach/*.h headers
  ARM: mv78xx0: multiplatform support
  ARM: mv78xx0: clean up mach/*.h headers
  ARM: orion: use SPARSE_IRQ everywhere
  ARM: orion: always use MULTI_IRQ_HANDLER
  ARM: orion: move watchdog setup to mach-orion5x
