linux-yocto/3.8: qemumips boot fixes and netfilter kernel features

Updating the linux-yocto-3.8 recipes to fix two issues:

1) qemumips boot

This is fixed by:

  Revert "Input: i8042-io - fix up region handling on MIPS"

And by disabling ftrace for qemumips boards

2) netfilter options being dropped

When KERNEL_EXTRA_FEATURES was introduced, and allowed to be
inhibited, the variable was only applied to qemux86 machines. It
should be applied ot all machine types (unless inhibited), so we
restore that functionality.
