[LEDE-DEV] [RFC] brcm47xx: bump kernel to 4.4

[p.wassi at gmx.at]

Hi there!

As one of LEDE's TODOs is "Bump all kernels to v4.4", I've done
some testing on two brcm47xx devices (brcm47xx is still on kernel 4.1).

The devices I tested on + bootlog:
Linksys WRT54GL - https://pwassi.privatedns.org/lede/brcm47xx/#wrt54gl
ASUS WL500gP V2 - https://pwassi.privatedns.org/lede/brcm47xx/#wl500gpv2

I know, that there are much more devices on brcm47xx which are untested yet.
However, these are the ones I have at home to play with and everything seems
to work fine there. So what do you think about the following 'patch'?

Best regards,
P. Wassi
