tests: Remove ARM compilation requirement for quick/Kokoro

The ARM Boot Tests required the compilation of ARM/gem5.opt to run a
quick test that the CHI protocol was functioning correctly with ARM and
the ArmBoard. This test has been removed and the test refactored
slightly to use the ALL/gem5.opt.

The CHI protocol is already tested nightly.
