kernel: b53: use hard coded switch reset gpio on some boards.
The Linksys wrt310n v1 does not have a robo_reset config variable in nvram, but GPIO Pin 8 is the pin needed for resetting the external switch, Linksys hard coded it into their source code. Thank you Devastator for testing. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> SVN-Revision: 37988
