This patchset add support for allwinner R40 AHCI controller.

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.

Patchs 1-7 should go via the ata tree
Patchs 8,9 should go via the sunxi tree
