intel_idle: PCI quirk to prevent Lenovo Ideapad s10-3 boot hang
commit 4731fdcf6f7bdab3e369a3f844d4ea4d4017284d upstream.
When the Lenovo Ideapad S10-3 is booted with HT enabled,
it hits a boot hang in the intel_idle driver.
This occurs when entering ATM-C4 for the first time,
unless BM_STS is first cleared.
acpi_idle doesn't see this because it first checks
and clears BM_STS, but it would hit the same hang
if that check were disabled.
