Qiang Yu 8b4d0f3890 bus: mhi: host: Skip MHI reset if device is in RDDM
commit cabce92dd8 upstream.

In RDDM EE, device can not process MHI reset issued by host. In case of MHI
power off, host is issuing MHI reset and polls for it to get cleared until
it times out. Since this timeout can not be avoided in case of RDDM, skip
the MHI reset in this scenarios.
