Subject: [PATCH v2 0/6] Minor bug fixes and clean-up for MHI host driver

This patch series serves to clean up the MHI host driver by removing an
unnecessary counter and an unused function. It also renames a function to make
it clearly worded. There is currently no user of this exported function which
makes it is safe to do so now.

Bug fixes include adding a missing EXPORT_SYMBOL_GPL to a function, and adding
a return value check to bail out of RDDM download in kernel panic path.

An outlier among the group exports the mhi_get_exec_env() API for use by
controller drivers, in case they need to determine behavior on the basis of the
current execution environment.

This set of patches was tested on arm64.

v2:
-Removed the declaration for mhi_get_exec_env() from internal.h
-Improved on the error log message in RDDM download exit case due to unknown EE
