Rob Clark 9d15962826 drm/msm: Do hw_init() before capturing GPU state
commit e4840d537c2c6b1189d4de16ee0f4820e069dcea upstream.

In particular, we need to ensure all the necessary blocks are switched
to 64b mode (a5xx+) otherwise the high bits of the address of the BO to
snapshot state into will be ignored, resulting in:

  *** gpu fault: ttbr0=0000000000000000 iova=0000000000012000 dir=READ type=TRANSLATION source=CP (0,0,0,0)
  platform 506a000.gmu: [drm:a6xx_gmu_set_oob] *ERROR* Timeout waiting for GMU OOB set BOOT_SLUMBER: 0x0

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.
