Hello

This patchset add support for allwinner R40 AHCI controller.

This controller need two regulator and one reset which is unsupported
for the moment on ahci_platform.

So this patchset add support for reset and regulator for AHCI
controller.
It add also support for non-target regulator per SATA port.

The whole patchset is tested on sun8i-r40-bananapi-m2-ultra and
on sun7i-a20-cubieboard2 which doesnt have any of the ressources added
by this serie, so no regression should come with it.

Since just before sending this patchset, I discovered the revert of
f0f56716fc3e ("ata: ahci-platform: add reset control support")
I have also tested this serie on a tegra124-jetson-tk1.

Changes since V2
- Moved all ressources management to ahci_platform
