DuetPkg: SataControllerDxe: fix private array subscripting
Each one of the DisqualifiedModes, IdentifyData and IdentifyValid arrays
in the EFI_SATA_CONTROLLER_PRIVATE_DATA structure is a matrix, represented
as a flat array.
The code currently uses the incorrect formula
Channel * Device
to index them. The right formula is
[Channel][Device]
which can be implemented as
Channel * NumDevicePerChannel + Device
Add a helper function that does this, and replace the incorrect
subscripts.
