drm: Remove the obsolete driver-r128

Commit 399516ab0fee ("MAINTAINERS: Add a bunch of legacy (UMS) DRM drivers")
marked r128 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
ATI Rage 128->drivers/gpu/drm/r128

It's time to remove this driver.
