Prabhakar Kushwaha 8b6934200c ata: ahci: Add shutdown to freeze hardware resources of ahci
commit 10a663a1b15134a5a714aa515e11425a44d4fdf7 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).
