Colin Xu 92010a9709 drm/i915/gvt: Fix mmio handler break on BXT/APL.
- Remove dup mmio handler for BXT/APL. Otherwise mmio handler will fail
  to init.
- Add engine GPR with F_CMD_ACCESS since BXT/APL will load them via
  LRI. Otherwise, guest will enter failsafe mode.

V2:
Use RCS/BCS GPR macros instead of offset.
Revise commit message.

V3:
Use GEN8_RING_CS_GPR macros on ring base.

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.
