dm: sata: dw_sata: Rename 'probe_ent' to uc_priv

With driver model this becomes uclass-private data. Rename the parameter
varable to reflect this.

With the driver model conversion we will not have any exported functions.
Move all exported functions to be together at the end of the file so that
we can deal with them in one #ifdef block.
