[PATCH] drm/amd/display: fix hdmi_encoded_link_bw definition

[Arnd Bergmann]

From: Arnd Bergmann <arnd at arndb.de>

Some of the data structures are hidden when CONFIG_DRM_AMD_DC_DCN is
disabled, which leads to a link failure:

      |                                                                            ^~~~~~~~~~~~~~~~~~~~

There is probably no need to hide the data structure, and removing
the #ifdef makes it build cleanly.
