In commit b24bb99d cp110 configuration initially done in u-boot
was removed and delegated to atf firmware as smc call.
That commit didn't account for later introduced in d13b740c SATA invert polarity support.

This patch adds support of passing SATA invert polarity flags to atf
firmware during the smc call.
