libahci: Allow drivers to override start_engine
Allwinner A10 and A20 ARM SoCs have an AHCI sata controller which needs a
special register to be poked before starting the DMA engine.
This register gets reset on an ahci_stop_engine call, so there is no other
place then ahci_start_engine where this poking can be done.
This commit allows drivers to override ahci_start_engine behavior for use by
the Allwinner AHCI driver (and potentially other drivers in the future).
