[PATCH] drm/doc: internals: remove section on PCI legacy support

[Randy Dunlap <rdunlap@infradead.org>]

The functions that were described in this section of
drm-internals.rst were removed in NOV-2023, along with all of the
kernel-doc comments in the source file. This now causes a
docs build warning, so remove that section of the documentation also.

drivers/gpu/drm/drm_pci.c:1: warning: no structured comments found

Fixes: 2504c7ec728b ("drm: Remove source code for non-KMS drivers")

-Bus-specific Device Registration and PCI Support
-------------------------------------------------
-
-A number of functions are provided to help with device registration. The
-functions deal with PCI and platform devices respectively and are only
-provided for historical reasons. These are all deprecated and shouldn't
-be used in new drivers. Besides that there's a few helpers for pci
-drivers.
