KVM: arm64: selftests: Add write_dbg{b,w}{c,v}r helpers in debug-exceptions

Browse source

Introduce helpers in the debug-exceptions test to write to
dbg{b,w}{c,v}r registers. Those helpers will be useful for
test cases that will be added to the test in subsequent patches.

No functional change intended.
