Hi Rob,

Could you please kindly comment on change below.

It allows board variants to be added easily via a simple define for different number of SATA ports.

Move remaining sata configuration to stingray-sata.dtsi and enable
ports based on NUM_SATA defined.
Now, all that needs to be done is define NUM_SATA per board.

Rob could you review this and let us know if this approach is okay or
not? Thank you!
