Subject: [PATCH 148/247] net: macb: Add default usrio config to default gem
config
There is no usrio config defined for default gem config leading to
a kernel panic devices that don't define a data. This issue can be
reprdouced with microchip polar fire soc where compatible string
is defined as "cdns,macb".
Fixes: edac63861db7 ("add userio bits as platform configuration")
