Prabhakar Kushwaha 9724b3f28d ata: ahci: Add shutdown to freeze hardware resources of ahci
commit 10a663a1b1 upstream.

device_shutdown() called from reboot or power_shutdown expect
all devices to be shutdown. Same is true for even ahci pci driver.
As no ahci shutdown function is implemented, the ata subsystem
always remains alive with DMA & interrupt support. File system
related calls should not be honored after device_shutdown().

So defining ahci pci driver shutdown to freeze hardware (mask
interrupt, stop DMA engine and free DMA resources).
