The NAS4229B and SQ201 Gemini systems have a PATA controller
which is linked to a SATA bridge in the SoC. Enable both
platforms to use the PATA/SATA devices.

ChangeLog v3->v4:
- No changes, just resending to keep the patch set together.
ChangeLog v2->v3:
- No changes, just resending to keep the patch set together.
- Cut the timings also from the second device instance.
ChangeLog v1->v2:
- Cut the timings - we open code these in the driver instead.
- Reference syscon node for clocks and resets as requested by
the devicetree reviewers.
- Use reset line #defines from the new header file.
PATA maintainers: this file will be applied by me through the ARM
SoC git tree. It is provided for reference only so you see how
it will be used.
