[PATCH v1 0/2] Serialize execution environment changes for MHI

[Bhaumik Bhatt <bbhatt@codeaurora.org>]

During full boot chain firmware download, the PM state worker downloads the AMSS
image after waiting for the SBL execution environment change in PBL mode itself.
Since getting rid of the firmware load worker thread, this design needs to
change and MHI host must download the AMSS image from the SBL mode of PM state
worker thread instead.

Also ensure that EE changes are handled only from appropriate places and occur
one after another and handle only PBL or RDDM EE changes as critical events
directly from the interrupt handler and the status callback is given to the
controller drivers promptly.

  bus: mhi: core: Download AMSS image from appropriate function
  bus: mhi: core: Process execution environment changes serially
