Improve error message to be more descriptive if a failure occurs with an invalid power up execution environment. Additionally, add a debug log to print the execution environment and MHI state before a power up is attempted to confirm if the device is in an expected state. This helps clarify reasons for power up failures such as the device being found in a PBL or Emergency Download Mode execution environment and the host expected a full power up with Pass-Through and no image loading involved.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
