When host connects a crt screen, linux guest will detect two
screens: crt and dp. This is wrong as linux guest has only
one dp.
In order to avoid guest get host crt screen, we should set
ADPA_CRT_HOTPLUG_MONITOR to none. But MMIO_RO(PCH_ADPA) prevent
from that. So MMIO_DH should be used instead of MMIO_RO.
v2: Clear its staus to none at initialize, so guest don't
get host crt.(Zhangyu)
v3: SKL doesn't have this register, limit it to pre_skl.(xiong)
