Subject: drm/r128: make ATI PCI GART part of its only user, r128
Git-commit: be14312472e93d0c9c8c3ea8ef7d4eb59ed73f8f
Patch-mainline: v5.6-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322

The ATI Rage 128 driver has been the only user of ATI PCI GART code
since Radeon dropped UMS support in commit 8333f607a631 ("drm/radeon:
remove UMS support"). Clean up the drm top level directory, Kconfig and
Makefile by making ati_pcigart.[ch] part of r128. Drop the
CONFIG_DRM_ATI_PCIGART config option made redundant by the change.

This reduces drm.ko module size slightly when legacy drivers are
enabled, and moves the baggage to r128.ko instead.
