drm/dp: Move DisplayPort helpers into separate helper module
Move DisplayPort functions into a separate module to reduce the size
of the KMS helpers. Select DRM_DP_HELPER for all users of the code. To
avoid naming conflicts, rename drm_dp_helper.c to drm_dp.c
This change can help to reduce the size of the kernel binary. Some
numbers from a x86-64 test build:
Before:
drm_kms_helper.ko: 447480 bytes
After:
drm_dp_helper.ko: 216632 bytes
drm_kms_helper.ko: 239424 bytes
For early-boot graphics, generic DRM drivers, such as simpledrm,
require DRM KMS helpers to be built into the kernel. Generic helper
functions for DisplayPort take up a significant portion of DRM KMS
helper library. These functions are not used by generic drivers and
can be loaded as a module.
v3:
* fix include statement in DRM selftests
v2:
* move DP helper code into dp/ (Jani)
