[PATCH net-next v2] net: macb: fix use of at91_default_usrio without CONFIG_OF

[Conor Dooley <conor@kernel.org>]

From: Conor Dooley <conor.dooley@microchip.com>

If CONFIG_OF is not enabled, at91_default_usrio is used undeclared in
gem_default_config. Move at91_default_usrio back above the CONFIG_OF
section where macb_default_usrio used to be, so that it is unconditionally
defined and defined prior to any of the users.

Closes: https://lore.kernel.org/all/06a701dcc014$86def5b0$949ce110$@trustnetic.com/
Fixes: a17871778ee28 ("net: macb: rename macb_default_usrio to at91_default_usrio as not all platforms have mii mode control in usrio")

lkp also reported this over the weekend, but against the dev copy in my
tree. I had thought that CONFIG_OF was standard off on x86, but I guess
it isn't, given lkp didn't catch it until randconfigs.

Seem to have come down with some sort of bug, hopefully I haven't cocked
this v2 up somehow in my addled state.

v2:
- Do the boring thing that works... Probably worth a revisit later, cos
  there's a bunch of confusing naming here still - "default_gem_config"
  is used for cdns,macb and of course "at91_default_usrio" is used on
  things where I am reasonably confident it shouldn't, like the Xilinx
  boards.
