x86/acpi/cstate: Optimize ARB_DISABLE on Centaur CPUs

zhaoxin inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I6SKA2


CVE: NA

----------------------------------------------------------

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.
