selftests/powerpc: Revert Load Monitor Register Tests

Load monitored won't be supported in POWER9, so PPC_FEATURE2_ARCH_3_00
(in HWCAP2) will no longer imply Load monitor support.

These Load monitored tests are enabled by PPC_FEATURE2_ARCH_3_00 so
they are now bogus and need to be removed.

This reverts commit 16c19a2e9833 ("selftests/powerpc: Load Monitor
Register Tests").

selftests/powerpc: Load Monitor Register Tests

Adds two tests. One is a simple test to ensure that the new registers
LMRR and LMSER are properly maintained. The other actually uses the
existing EBB test infrastructure to test that LMRR and LMSER behave as
documented.

git ignores all of these test binaries when displaying status.
