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").
