Previous commits carved out some TX configuration from different places
into a dedicated function. A cause of this is a behavioral change where
the TX amplifier values aren't applied anymore if it isn't a "fiber
mode". To restore this behavior and make the media/TX-RX configuration
more generic, we need a dedicated media type. The existing ones only
cover fiber and DACs, but not the other left case where a PHY is
attached to the SerDes. This now calls set_media for USXGMII and XSGMII
modes intentionally, both to prepare for future changes and to restore
previous behavior.
We do not have a reliable way to distinct between the actually used
media types, this is still a TODO. But several parts of the code already
have different values applied based on this information. Moreover, this
is especially needed for DAC cables to work properly. While this is
missing, we need to rely on inferring the media from the SerDes mode.
While at it, improve the call site of media handling since there's a
media type for all cases now. This allows to reduce the number of
function calls by moving it out and just have the media type in the
decision block.
