cs5520: add enablebits checking
Based on sparse comments in OpenFirmware code (no Cx5510/Cx5520 datasheet here). This fixes 2.6.26 regression reported by TAKADA and caused by addition of warm-plug support. Tested-by: TAKADA Yoshihito <takada@mbf.nifty.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
