This patch lets the user enable support for EVKLCD100 and EVKLCD101 (refered to by EVKLCD10X). By enabling EVKLCD10X support the LCD controller and AC97 controller platform devices are added. The user can also choose between the EVKLCD100 (QVGA display) and the EVKLCD101 (VGA display), this is added to automagically select the correct panel timing and resolution parameters. Enabling support for EVKLCD10X addon board will cripple the MCI platform device a bit since they share two GPIO lines (detect and write-protect). These two lines are disabled when EVKLCD10X is enabled. The default configurations are based upon ATNGW100, but with added AC97C and LCDC driver. Virtual terminal is also enabled by default for EVKLCD10X boards. Verified on hardware with a NGW100 + EVKLCD100/101.
