I would be inclined to apply this hack and make it bcm63xx specific
unless other platforms suffer from that problem.

Meanwhile, I would reach out to the MTD maintainers to understand what
is going on, mentioning what we have found, which is that the brcmnand
controller prior to version 4.0 does not support the {GET,SET}_FEATURES
command.
