juhosg b95eb02775 ramips: initial support for Sitecom WL-351 v1 002
This add support for the Sitecom WL-351 v1 002.
In principle the Engenius ESR9850 should also work with this, but I
don't have the hardware to test it.

Since an external gigabit switch (RTL8366RB) is used,
I had to modify the ramips_esw driver to add a 'bypass' mode, which
just configures it to not filter the vlan tags.
Also two initialization words (FCT2 and FPA2) are set to different
values by u-boot than what the driver is using and it only seems to
work correctly when they not overridden by the driver, so I
added them to the platform specific data as reg_initval_fct2 and
reg_initval_fpa2.

With this wired lan works as expected, however I'm still having some
trouble with the wireless lan:
It only works after I rmmod & re-insmod rt2800pci and then
reconfigure it in the webinterface, but not directly after
rebooting.

The symptom of this is wpad saying:
Dec 20 15:45:09 OpenWrt daemon.info hostapd: wlan1: STA <notebookmac> IEEE 802.11: associated (aid 1)
Dec 20 15:45:09 OpenWrt daemon.info hostapd: wlan1: STA <notebookmac> WPA: pairwise key handshake completed (RSN)
Dec 20 15:45:22 OpenWrt daemon.info hostapd: wlan1: STA <notebookmac> IEEE 802.11: authenticated

But wpa_supplicant on the client saying:
Authentication with <wl351mac> timed out.
