dev-arm: Add new VExpress_GEM5_V1_Base Platform

Add a new VExpress_GEM5_V1_Base Platform which configures basic on
chip devices. The original VExpress_GEM5_V1 will inherit the Base and
add more on chip devices (currently only the HDLCD). This change will
make it possible to create variations of the base platform with
different devices.
