vexpress64: defconfigs: allow default commands

Right now the defconfig the Arm VExpress64 boards disables quite some
standard commands, for apparently no good reasons (as image size is
hardly a concern here).

Remove the lines explicitly disabling those features, leaving it to
the U-Boot default settings to set them.
