[OpenWrt-Devel] [PATCH] mpc85xx: TL-WDR4900: Fix port 6 being shown as up (10MBit/half) in LUCI/swconfig

Currently port 6 is shown as up 10MBit/half in LUCI and swconfig.
Reason is that all bits in the port 6 config are zero.
This means that also the aneg flag is not set and in this case
ar8216_read_port_link hardcodes the link to be up.

This is no real problem but a little annoying.
To fix this initialize port 6 with the aneg bit enabled.
This causes ar8216_read_port_link to evaluate the link status bit which is
always zero for port 6 as no PHY is connected to this port.
And it doesn't hurt as port 6 isn't connected to anything on TL-WDR4900.
