Subject[PATCH v5 6/9] ata: ahci_sunxi: add support for r40
Date
This patch add the r40 compatible to the ahci_sunxi's supported list of
compatible.

Since R40 need ahci_platform to handle the reset controller, we also add
the new AHCI_PLATFORM_GET_RESETS flag for ahci_platform_get_resources().
This has no consequence for older platform (a10, a20) since the reset is
optional.
