mb/asrock/g41c-gs: Rename the board to G41C-GS R2.0 (g41c-gs_r2_0).

The supported "G41C-GS" with a nuvoton nct6776 superio is actually
G41C-GS R2.0, which is different with the more easily-found revision
G41C-GS (R1.0) with Winbond W83627DHG superio, and should be ported
separately.

Photos for the two revision:
