The SATA related PCDs consumed by AmdSataInitLib contain a PcdSataPortMode PCD that sets the port mode to all ports. This PCD defaults to zero, while the code in question has no default, i.e., the value 0 is not treated as either 1, 2 or 3, and so the init sequence is not carried out correctly.
While observed SATA link detection issues on CelloBoard appear to be unrelated to this (i.e., this change did not improve the situation), let's set the correct values nonetheless.
