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.

drm/amd/display: Fix reg timeout in enc314_enable_fifo [Why] The link enablement sequence can end up resetting the encoder while the PHY symclk isn't yet on. This means that waiting for symclk on will timeout, along with the reset bit never asserting high. This causes unnecessary delay when enabling the link and produces a warning affecting multiple IGT tests. [How] Don't wait for the symclk to be on here because firmware already does. Don't wait for reset if we know the symclk isn't on. Split the reset into a helper function that checks the bit and decides whether or not a delay is sufficient.
