mb/acer/g43t-am3: Add Acer Q45T-AM as a variant
This adds a new board as a variant of the Acer G43T-AM3 with the following prominent changes: * Intel Q45 northbridge (GMCH) instead of a G43 * 4 MiB of flash instead of 2 MiB * Two serial ports (one external, one internal) * A parallel port connector (internal) * An FDD connector * DVI-D instead of HDMI * No Firewire The port was done based on logs and info received via private email. It was only tested on the Acer G43T-AM3 so far, which still builds and works.
