[PATCH v2 0/3] hw/arm: Add support for USB, SATA, and watchdog to Allwinner R40

[Guenter Roeck]

Add support for

- USB 2.0 EHCI/OHCI
- SATA/AHCI
- Watchdog

to Allwinner R40. The hardware is quite similar to Allwinner A10 and H3,
so the code is derived from the implementations for those SOCs.

Tested with bpim2u emulation by instantiating EHCI and OHCI keyboards,
by booting from USB, by booting from ATA/SATA drive, and by manually
testing watchdog operation.

v2:
- The USB Controllers are part of the chipset, so instantiate them
  unconditionally
- Add Reviewed-by: tag to patch 2/3
