The bf537-stamp shouldn't need this SPI flash workaround. It was added by accident a long time ago through a convoluted series of steps which originated from a customer board (not the bf537-stamp). So drop it to keep people from incorrectly adding it to their own boards. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
