This adds a new vGPU cap info bit VGT_CAPS_HUGE_GTT, which is to detect
whether the host supports shadowing of huge gtt pages. If host does
support it, remove the page sizes restriction for vGPU.

Guest OS driver uses PV info registers to deliver cursor hotspot info
to host. This patch is used to get cursor hotspot info from virtual
registers and deliver it to host userspace.
v4->v5:
- remove CI warning.
v3->v4:
- return UINT_MAX when x_hot/y_hot is invalid. (Zhenyu)
- correct version.
v2->v3:
- add validate_hotspot(). (Zhenyu)
v1->v2:
- name as cursor_x_hot/cursor_y_hot. (Zhenyu)
- use i915_reg_t definition instead of magic numbers. (Zhenyu)

Let GVT-g VM read the CSB and CSB write pointer from virtual HWSP, not all
the host support this feature, need to check the BIT(3) of caps in PVINFO.
v3 : Remove unnecessary comments.
v4 : Separate VM enable patch with GVT-g implementation patch due to code
dependency.
v5 : Use inline for GVT virtual HWSP caps check function.
v6 : Comments refine.

Enable the guest i915 full ppgtt functionality when host can provide this
capability. vgt_caps is introduced to guest i915 driver to get the vgpu
capabilities from the device model. VGT_CPAS_FULL_PPGTT is one of the
capabilities type to let guest i915 dirver know that the guest i915 full
ppgtt is supported by device model.
Notice that the minor version of pvinfo isn't bumped because of this
vgt_caps introduction, due to older guest would be broken by simply
increasing the pvinfo version. Although the pvinfo minor version doesn't
increase, the compatibility won't be blocked. The compatibility is ensured
by checking the value of caps field in pvinfo. Zero means no full ppgtt
support and BIT(2) means this feature is provided.
Changes since v1:
- Use u32 instead of uint32_t (Joonas)
- Move VGT_CAPS_FULL_PPGTT introduction to this patch and use #define
instead of enum (Joonas)
- Rewrite the vgpu full ppgtt capability checking logic. (Joonas)
- Some coding style refine. (Joonas)
Changes since v2:
- Divide the whole patch set into two separate patch series, with one
patch in i915 side to check guest i915 full ppgtt capability and enable
it when this capability is supported by the device model, and the other
one in gvt side which fixs the blocking issue and enables the device
model to provide the capability to guest. And this patch focuses on guest
i915 side. (Joonas)
- Change the title from "introduce vgt_caps to pvinfo" to
"Enable guest i915 full ppgtt functionality". (Tina)
Change since v3:
- Add some comments about pvinfo caps and version. (Joonas)
Change since v4:
- Tested by Tina Zhang.
Change since v5:
- Add limitation about supporting 32bit full ppgtt.
Change since v6:
- Change the fallback to 48bit full ppgtt if i915.ppgtt_enable=2. (Zhenyu)
Change in v9:
- Remove the fixme comment due to no plan for 32bit full ppgtt
support. (Zhenyu)
- Reorder the patch-set to fix compiling issue with git-bisect. (Zhenyu)
- Add print log when forcing guest 48bit full ppgtt. (Zhenyu)
v10:
- Update against Joonas's has_full_ppgtt and has_full_48bit_ppgtt disconnect
change. (Zhenyu)

Current it's strictly checked if PVINFO version matches 1.0
for GVT-g i915 guest which doesn't help for compatibility at
all and forces GVT-g host can't extend PVINFO easily with version
bump for real compatibility check.
This fixes that to check minimal required PVINFO version instead.
v2:
- drop unneeded version macro
- use only major version for sanity check
v3:
- fix up PVInfo value with kernel type
- one indent fix

To get the offset of the members in PVINFO page, offsetof() looks much
better than the tricky approach in current code.

As the PVINFO page definition is used by both GVT-g guest (vGPU) and GVT-g
host (GVT-g kernel device model), factor it out for better code structure.
v7:
- Split the "offsetof" modification into a dedicated patch. (Joonas)
v3:
- Use offsetof to calculate the member offset of PVINFO structure (Joonas)
