arm,config: Added the VExpress_GEM5_V1_64 platform
With this change, now VExpress_GEM5_V1 is only for aarch32, and the new
VExpress_GEM5_V1_64 platforms is only for aarch64.
VExpress_GEM5_V1_64 is basically a subclass of VExpress_GEM5_V1, and it
only overrides the necessary methods to setup an aarch64 bootloader and
tell that it is aarch64 in order to set highest_el_is_64 to True.
This mechanism for setting highest_el_is_64 is also used by VExpress_EMM64,
which was not setting it by default.
Basic regression tests have been added for both VExpress_GEM5_V1* platforms.
These tests rely on the up-to-date ARM FullSystem files from here:
https://github.com/metempsy/gem5_arm_fullsystem_files_generator/releases/download/20170421/aarch-system-20170421.tar.xz
Updated the default kernel and DTBs to be used by the VExpress_EMM and
VExpress_EMM64 platforms in order to use the up-to-date ones from above.
If not found, fall back to the old names.
