bus: mhi: core: Handle EDL mode entry appropriately
Device entering EDL or Emergency Download Mode will be in a
SYS_ERROR MHI state. This requires MHI host to proceed with the
EDL image download over BHI before device can enter an MHI READY
state and proceed with further bootup. Allow this to be handled
by relying on the execution environment check after SYS_ERROR
processing to determine whether to wait for an MHI READY or
download the EDL image over BHI after moving MHI PM state to
Power on Reset internally. This way handling is contained well
within the MHI core driver and helps pave the way for Flash
Programmer execution environment functionality.
