brcm47xx: add kernel 4.14 support
Add patches for 4.14, drop patch 030 since it's already included upstream. Tested on: 1) WRT54GL (with RAM upgraded to 32 MiB) 2) WL500gPv2 (with RAM upgraded to 64 MiB) 3) BCM47186B0 SoC board 4) BCM4706 SoC board Signed-off-by: Paul Wassi <p.wassi@gmx.at> Signed-off-by: Rafał Miłecki <rafal@milecki.pl>
