[PATCH RFT v2] drm/msm/dpu: enable virtual planes by default

[Dmitry Baryshkov]

Turn on the switch and use virtual planes by default, enhancing
utilisation of the display pipelines. It is still possible to use legacy
implementation by using `msm.dpu_use_virtual_planes=false` kernel boot
parameter.

This is being sent as an RFT for now. Please give it a test with your
compositor of choice. X11. Weston. Sway. Wlroot. CrOS. I plan to turn
the switch for 7.1

Changes in v2:
- Rebased on msm-next
- Updated the cover letter, targeting the switch to 7.1
- Link to v1: https://lore.kernel.org/r/20250514-dpu-enable-virt-planes-v1-1-bf5ba0088007@xxxxxxxxxxxxxxxx
