ssb: Fix all-ones boardflags
commit 4503183aa32e6886400d82282292934fa64a81b0 upstream
In the SSB SPROM a field set to all ones means the value
is not defined in the SPROM.
In case of the boardflags, we need to set them to zero
to avoid confusing drivers. Drivers will only check the
flags by ANDing.
