Just evict unpinned objects to system. For pinned LMEM objects,
make a backup system object and blit the contents to that.

Backup is performed in three steps,
1: Opportunistically evict evictable objects using the gpu blitter.
2: After gt idle, evict evictable objects using the gpu blitter. This will
be modified in an upcoming patch to backup pinned objects that are not used
by the blitter itself.
3: Backup remaining pinned objects using memcpy.

In discrete cards, the graphics driver shouldn't proceed with the probe
or resume unless PCODE indicated everything is done, including memory
training and gt bring up.

For this reason, the driver probe and resume paths needs to be blocked
until PCODE indicates it is done. Also, it needs to aborted if the
notification never arrives.

In general, the few miliseconds would be enough and the regular PCODE
recommendation for the timeout was 10 seconds. However there are some
rare cases where this initialization can take up to 1 minute. So,
PCODE has increased the recommendation to 3 minutes so we don't fully
block the device utilization when something just got delayed for
whatever reason. To be on the safest side, let's accept this
recommendation, since on the regular case it won't delay or block the
driver initialization and resume flows

Switch ICL to use a revid->stepping table as we're trying to do on all
platforms going forward.  While we're at it, let's include some
additional steppings that have popped up, even if we don't yet have any
workarounds tied to those steppings (we probably need to audit our
workaround list soon to see if any of the bounds have moved or if new
workarounds have appeared).

Note that the current bspec table is missing information about how to
map PCI revision ID to GT/display steppings; it only provides an SoC
stepping.  The mapping to GT/display steppings (which aren't always the
same as the SoC stepping) used to be in the bspec, but was apparently
dropped during an update in Nov 2019; I've made my changes here based on
an older bspec snapshot that still had the necessary information.  We've
requested that the missing information be restored.

I'm only including the production revids in the table here since we're
past the point at which we usually stop trying to support pre-production
hardware.  An appropriate check is added to
intel_detect_preproduction_hw() to print an error and taint the kernel
just in case someone still tries to load the driver on old
pre-production hardware.

v2:
 - Drop pre-production steppings and add error/taint at startup when
   loading on pre-production hardware.

Although we're converting our workarounds to use a revid->stepping
lookup table, the function that detects pre-production hardware should
continue to compare against PCI revision ID values directly.  These are
listed in the bspec as integers, so it's easier to confirm their
correctness if we just use an integer literal rather than a symbolic
name anyway.

Replace gen with the new graphics_ver value and use GRAPHICS_VER()
in those places.

Now that it's not used anywhere, remove it from struct
intel_device_info. To allow a period in which code will be converted to
the new macro, keep IS_GEN_RANGE() around, just redefining it to use
the new fields. The size advantage from IS_GEN_RANGE() using a mask is
not that big as it has pretty limited use througout the driver:

Display features should not be initialized or de-initialized when there
is no display. Skip modeset initialization, output setup, plane, crtc,
encoder, connector registration, display cdclk and rawclk
initialization, display core initialization, etc.

Skip the functionality at as high level as possible, and remove any
redundant checks. If the functionality is conditional to *other* display
checks, do not add more. If the un-initialization has checks for
initialization, do not add more.

We explicitly do not care about any GMCH/VLV/CHV code paths, as they've
always had and will have display.

We need to wait for the DMC FW loader work to complete during shutdown,
even if it's unlikely to be still pending by that time, fix this.

This also fixes the wakeref tracking WARN during shutdown about the
leaked reference we hold due to a missing DMC firmware.

While at it add a TODO comment about unifying the shutdown and PM
power-off sequences and later these sequences with the driver remove and
system/runtime suspend sequences.

Add new symbolic names for revision ids, and convert KBL revids to use
them via the new stepping check macros.

This also fixes theoretical out of bounds access to kbl_revids array.

v3: upgrade dbg to warn on unknown revid (José)

v2: Rename stepping->step
