ar71xx: add kernel support for the EnGenius ESR900
Signed-off-by: Forest Crossman <cyrozap@gmail.com> Patchwork: http://patchwork.openwrt.org/patch/5714/ [juhosg: - drop nvram.c modifications, - create a separate kernel patch, - use ath79_setup_qca955x_eth_cfg helper, - merge esr900_{010,common}_setup functions, - statically init AR8327 pad configurations, - use pr_err instead of printk] Signed-off-by: Gabor Juhos <juhosg@openwrt.org> SVN-Revision: 41640
