Transfer of GuC firmware requires few steps that currently
are implemented in two large functions. Split this code into
smaller functions to make these steps small and clear.
Also be prepared for potential DMA xfer step failure.

v2: rename function steps (Sagar)

* [PATCH v4 1/5] drm/i915/guc: Move GuC WOPCM related code into separate files
@ 2017-12-12 22:56 Jackie Li

intel_guc_reg.h should only include definition for GuC registers
and related register bits. GuC WOPCM related values should not
be defined in intel_guc_reg.h

This patch creates a better file structure by moving GuC WOPCM
related definitions int to a new header intel_guc_wopcm.h
and moving GuC WOPCM related functions to a new source file
intel_guc_wopcm.c
