[PATCH 1/4] Drivers/SataSiI3132Dxe: Fixed PCI IO read and write operations

[Daniil Egranov <daniil.egranov@arm.com>]

The ATA pass through read should use PCI IO bus master write operation
and ATA pass through write should use PCI IO bus master read operation
as the read and write operations executed from the bus master's point
of view.
