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.
