The ahci_platform driver is a generic driver using the libahci_platform functions. Add a generic compatible to avoid having an endless list of compatibles with no differences for the same driver.

I'm not against this, I've introduced the same for the ehci / uhci platform driver after all, but this should be documented in Documentation/devicetree, and please make sure to mention in the docs that the correct way to use this inside a dts file is: compatible = "manufacturer,soc-model-ahci", "generic-ahci"; So that we can later add quirks for the specific soc if necessary without needing to change the dts.
