brcm2708: Adapt patches to kernel update 

In kernel 4.4.182 get_user_pages() does not get the write and force
parameter any more, but one flags parameter with WRITE and FORCE
attributes. This adapts the patches to use the changed API and fixes
the compile problems with the brcm2708 target.

This fixes the following compile problem:
