Subject: [RESEND PATCH linux-next v2 01/10] drm: Remove the obsolete driver-i810

Commit 399516ab0fee ("MAINTAINERS: Add a bunch of legacy (UMS) DRM drivers")
marked i810 driver obsolete 7 years ago.
And the mesa UMD of this drm driver already in deprecated list
in the link: https://docs.mesa3d.org/systems.html
Intel i810-->driver/gpu/drm/i810

It's time to remove this driver.
