Fei Li df3390f401 hv: vtd: reset the one-shot bits for GCMD_REG ... If multiple control fields in GCMD_REG register need to be modified, software must serialize the modifications through multiple writes to this register. So one-shot bits (bits 30-29, 27 and 24) in gcmd should not been set. Otherwise, other control field may be written to GCMD_REG at the same time with one-shot bit (Clearing one-shot bit has no effect, software sets this field would set/update this control field used by hardware).
