keernel: Fixed dependencies in netfilter modules introduced with 3.18 kernel

Building current trunk with 3.18 kernel fired some errors like 'missed
dependancy of module XXX from library kmod_YYY.ko'. These patch fixes 3
of such issues which are critical to have a successful build.

gemini: add basic nas4220 board support

Few notes:
- redboot partitions are unusable
- redboot declares only 16M of RAM, hence the mem arg in cmdline and separate kernel config
- boots fine but only ethernet works for now
- split wiliboard and raidsonic boards into different subtargets

ixp4xx: Don't overwrite memory in wg302v1_fixup()

wg302v1_fixup() looks for the ATAG_CMDLINE atag, it doesn't find it and
so it takes the last atag in the list and overwrites non allocated
memory.

The side effects are corrupted vital data and a kernel that doesn't
boot. More details here https://dev.openwrt.org/ticket/18356

The fix appends the fixup to the command line and updates the atag only
when it finds it.
