mb/amd/chausie: add mainboard as copy of mb/amd/majolica
To have the new AMD Sabrina SoC code tested, add the AMD Chausie
mainboard as a copy of Majolica. This patch also changes the name from
Majolica to Chausie, selects the Sabrina SoC instead of the Cezanne SoC
and comments out the APCB_SOURCES since those aren't available in the
3rdparty/blobs repository yet.
