DRM driver for hyperv synthetic video device, based on hyperv_fb
framebuffer driver. Also added config option "DRM_HYPERV" to enabled
this driver.
v2:
- Add support for gen2 VM
- Fixed review comments
v3:
- Split into multiple files as suggested by Thomas Zimmermann
- Fixed hibernation issue as suggested by Dexuan Cui
- Use ioremap_cache as suggested by Dexuan Cui
- Incorporated other review comments
v4:
- Fix bitrotted code
- Review comments
- Updated the copyright and license to match hyperv_fb
v5:
- Address review comments and rebased with drm-misc-next
v6:
- Minor code/comment improvement as suggested by Dexuan Cui

We are calling the eviction_valuable driver callback at eviction time to
determine whether we actually can evict a buffer object.
The upcoming i915 TTM backend needs the same functionality for swapout,
and that might actually be beneficial to other drivers as well.
Add an eviction_valuable call also in the swapout path. Try to keep the
current behaviour for all drivers by returning true if the buffer object
is already in the TTM_PL_SYSTEM placement. We change behaviour for the
case where a buffer object is in a TT backed placement when swapped out,
in which case the drivers normal eviction_valuable path is run.

If the bo is idle when calling ttm_bo_pipeline_gutting(), we unnecessarily
create a ghost object and push it out to delayed destroy.
Fix this by adding a path for idle, and document the function.
Also avoid having the bo end up in a bad state vulnerable to user-space
triggered kernel BUGs if the call to ttm_tt_create() fails.
Finally reuse ttm_bo_pipeline_gutting() in ttm_bo_evict().

Reading out of write-combining mapped memory is typically very slow
since the CPU doesn't prefetch. However some archs have special
instructions to do this.
So add a best-effort memcpy_from_wc taking dma-buf-map pointer
arguments that attempts to use a fast prefetching memcpy and
otherwise falls back to ordinary memcopies, taking the iomem tagging
into account.
The code is largely copied from i915_memcpy_from_wc.

The internal ttm_bo_util memcpy uses ioremap functionality, and while it
probably might be possible to use it for copying in- and out of
sglist represented io memory, using io_mem_reserve() / io_mem_free()
callbacks, that would cause problems with fault().
Instead, implement a method mapping page-by-page using kmap_local()
semantics. As an additional benefit we then avoid the occasional global
TLB flushes of ioremap() and consuming ioremap space, elimination of a
critical point of failure and with a slight change of semantics we could
also push the memcpy out async for testing and async driver development
purposes.
A special linear iomem iterator is introduced internally to mimic the
old ioremap behaviour for code-paths that can't immediately be ported
over. This adds to the code size and should be considered a temporary
solution.
Looking at the code we have a lot of checks for iomap tagged pointers.
Ideally we should extend the core memremap functions to also accept
uncached memory and kmap_local functionality. Then we could strip a
lot of code.

Currently only linear formats are supported in sun4i-drm driver, but
SoCs like H6 supports AFBC variant of some of them in multiple cores
(GPU, VPU, DE3). Panfrost already implements AFBC compression and is
sometimes confused what should be default choice (linear, AFBC) if DRM
driver is not explicit about modifier support (MiniMyth2 distro with
MythTV app).
After some discussion with Daniel Stone on #panfrost IRC, it was decided
to make modifiers in sun4i-drm explicit, to avoid any kind of guessing,
not just in panfrost, but everywhere. In fact, long term idea is to make
modifier parameter in drm_universal_plane_init() mandatory (non NULL).

If the of_get_named_gpio_flags call fails in vc4_hdmi_bind, we jump to
the err_unprepare_hsm label. That label will then call
pm_runtime_disable and put_device on the DDC device.
We just retrieved the DDC device, so the latter is definitely justified.
However at that point we still haven't called pm_runtime_enable, so the
call to pm_runtime_disable is not supposed to be there.
