I am not entirely sure whether loading values from Device Tree should
be considered a PHY fixup per-se. They do override the hardware reset
default values, but I am not sure if we should consider that as a
fixup.

Assuming that you need to troubleshoot a given system, one of the
first things you will surely ask for is the DTS used by that platform,
and in that case you can quickly check whether the PHY default
settings are changed, right?

There is no need for the else here

Same here
