!428 [openEuelr-1.0-LTS] x86/acpi/cstate: Optimize ARB_DISABLE on Centaur CPUs

Merge Pull Request from: @leoliu-oc 
 
On all recent Centaur platforms, ARB_DISABLE is handled by PMU automatically
while entering C3 type state. No need for OS to issue the ARB_DISABLE,
so set bm_control to zero to indicate that.
