Len Brown 79d05ce04b intel_idle: prevent SKL-H boot failure when C8+C9+C10 enabled
commit d70e28f57e14a481977436695b0c9ba165472431 upstream.

Some SKL-H configurations require "intel_idle.max_cstate=7" to boot.
While that is an effective workaround, it disables C10.

This patch detects the problematic configuration,
and disables C8 and C9, keeping C10 enabled.

Note that enabling SGX in BIOS SETUP can also prevent this issue,
if the system BIOS provides that option.
