Tony, after corrections, as this is a fix could be included ? Or we
need to wait to the next merge window.
The problem is, with recent u-boot these pins are not muxed because
u-boot sets only the minimum required for uboot functionality and
kernel boot. In kernel these pins must be muxed in order to get the
wifi and bluetooth work.
