[ Upstream commit b12422362ce947098ac420ac3c975fc006af4c02 ]
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")
