ArchLinux Manjaro Broadcom Wireless - Channel 12 + 13

Problem: On Manjaro (ArchLinux) there are only WLAN channels available up to 11, which is US standard, but not European.
I also could see this problem on Linux Mint and Xubuntu, but not on grml. Drivers like b43, broadcom-wl STA firmware could not give me success. What I did, after many tries failed (compiled own regulatory.bin, playing with crda, iw reg set, ...)

Uninstalled some packages:
  pacman -Ru crda
  pacman -Ru linux318-broadcom-wl
  pacman -Ru zd1211-firmware
  pacman -Ru wireless-regdb
  pacman -Ru ipw2200-fw
  pacman -Ru b43-fwcutter
  pacman -Ru ipw2100-fw

Removed manjaro hardware config:
mhwd -r pci network-broadcom-wl

lspci -vnn -d 14e4:
... Broadcom Corporation BCM43225 802.11b/g/n [14e4:4357] (rev 01)

After restart I could see Channel 13 (iwlist scan | grep Channel:)
iwlist chan also shows 13 channels.
