All other parameters can be extracted from a single struct xe_hw_engine
reference. This removes redundancy and simplifies the code.

DRM_ERROR() has been deprecated in favor of pr_err(). However, we should
prefer to use xe_gt_err() or drm_err() whenever possible so we get gt-
or device-specific output with the error message.
v2:
- Prefer drm_err() over pr_err(). (Matt, Jani)
v3:
- Prefer xe_gt_err() over drm_err() when possible. (Matt)
v4:
- Use the already available dev variable instead of xe->drm as
parameter to drm_err(). (Matt)

Now that struct xe_reg and struct xe_reg_mcr are types that can be used
by xe, convert more of the driver to use them. Some notes about the
conversions:
- The RTP tables don't need the MASKED flags anymore in the
actions as that information now comes from the register
definition
- There is no need for the _XE_RTP_REG/_XE_RTP_REG_MCR macros
and the register types on RTP infra: that comes from the
register definitions.
- When declaring the RTP entries, there is no need anymore to
undef XE_REG and friends: the RTP macros deal with removing
the cast where needed due to not being able to use a compound
statement for initialization in the tables
- The index in the reg-sr xarray is the register offset only.
Otherwise we wouldn't catch mistakes about adding both a
MCR-style and normal-style registers. For that, the register
is now also part of the entry, so the options can be compared
to check for compatible entries.
In order to be able to accomplish this, some improvements are needed on
the RTP macros. Change its implementation to concentrate on "pasting a prefix
to each argument" rather than the more general "call any macro for each
argument". Hopefully this will avoid trying to extend this infra and
making it more complex. With the use of tuples for building the
arguments, it's not possible to pass additional register fields and
using xe_reg in the RTP tables.
xe_mmio_* still need to be converted, from u32 to xe_reg, but that is
left for another change.

Add debugfs entry to dump the final tables with register save-restore
information.
For the workarounds, this has a format a little bit different than when the
values are applied because we don't want to read the values from the HW
when dumping via debugfs. For whitelist it just re-uses the print
function added for when the whitelist is being built.

The dump function was originally added with the idea that it could be
re-used both for printing the reg-sr data and saving it to pass to GuC
via ADS. This was not used by the GuC integration, so remove it now to
give place to a new debug.

Xe, is a new driver for Intel GPUs that supports both integrated and
discrete platforms starting with Tiger Lake (first Intel Xe Architecture).
The code is at a stage where it is already functional and has experimental
support for multiple platforms starting from Tiger Lake, with initial
support implemented in Mesa (for Iris and Anv, our OpenGL and Vulkan
drivers), as well as in NEO (for OpenCL and Level0).
The new Xe driver leverages a lot from i915.
As for display, the intent is to share the display code with the i915
driver so that there is maximum reuse there. But it is not added
in this patch.
This initial work is a collaboration of many people and unfortunately
the big squashed patch won't fully honor the proper credits. But let's
get some git quick stats so we can at least try to preserve some of the
credits:
