Subject: [PATCH v2 3/3] ata: ahci_platform: enable to get and control reset

Unlike SoC-specific driver, generic ahci_platform driver doesn't
have any chances to control resets.

This adds AHCI_PLATFORM_GET_RESETS to ahci_platform_get_resources()
on the generic driver to enable reset control support.
