lantiq: fix etop registers

lantiq: fix etop registers

As first reported more than a year ago
(https://lists.openwrt.org/pipermail/openwrt-devel/2012-August/016240.html
and
https://lists.openwrt.org/pipermail/openwrt-devel/2012-August/016241.html),
some of the register definitions of the lantiq etop driver are
incorrect. When OpenWrt is booted with a bootloader which doesn't do
proper network initialization of its own (e.g. brnboot), ethernet won't
work. The patch below changes the register names and addresses to match
the lantiq etop driver included with the recent U-Boot.

At the moment the MII/RMII setting in the lantiq .dts-files has no
effect, since wrong registers are written. Once this patch is applied,
it is necessary to make sure that the MII/RMII setting in the .dts-file
is correct.

v2: fix mangled whitespaces
