ArmPlatformPkg: Add support for PL111 Lcd driver
This driver implements the interface for the PL111 Lcd controller. The LcdPlatformLib allows to set the platform specific requirements needed by the platform for setting the LCD (oscillators, etc). ArmPlatformPkg/ArmVExpressPkg: Implement LcdPlatformLib This library exports the supported resolutions. It also allocates the memory for the framebuffer and send the correct settings to the VExpress motherboard microcontroller. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11786 6f19259b-4bc3-4df7-8a09-765794883524
