98ce7d32e2 drm/amd/display: convert link.h functions to function pointer style 
[Why & How]
All dc subcomponents should call another dc component via function pointers
stored in a component structure. This is part of dc coding convention since
the beginning. The reason behind this is to improve encapsulation and
polymorphism. The function contract is extracted into a single link service
structure defined in link.h header file and implemented only in link_factory.c instead
of spreading across multiple files in link component file structure.

54618888d1 drm/amd/display: break down dc_link.c 
[why]
dc_link contains over 30k line of code, the decision is to break it
down to files residing in link folder based on functionality. This
change is the last break down change which will remove dc_link.c
file after everything is broken down.

[how]
Move remaining dc_link.c functions into link_detection, link_dpms,
link_validation, link_resource, and link_fpga and remove dc_link.

6ca7415f11 drm/amd/display: merge dc_link_dp into dc_link 
[why]
Temporarly merge dc_link_dp functions into dc_link for the
purpose of removing dc_link_dp files. This is a transitional
change for later commits where we will further refactor dc_link
file.

bc33f5e5f0 drm/amd/display: create accessories, hwss and protocols sub folders in link 
[why]
link component contains three sub folders:

accessories - utilities for improving testability, logging or tracing, doesn't impact
end user use cases.

protocols - specs defined protocols used in end user use cases

hwss - hwss owned link_hwss object, served as an abstraction layer in hwss to
access various types of encoder/phy/dpia endpoints in a unified interface.

sooner we will have files directly under link folder one for the implementation of
each major link behavior such as link_create, link_detect, link_validate
and link_set_dpms.
