[TESTME] nb/intel/ironlake: Fix some quickpath init magic

TO TEST: Check that Arrandale (mobile Ironlake) still works.

Correct some Quickpath initialisation steps according to findings from
two different Intel reference code binaries as well as MCHBAR register
dump comparisons between vendor firmware and coreboot.

Tested on Apple iMac 10,1 (Clarkdale, aka desktop Ironlake), QPI init
now completes successfully instead of causing hangs before raminit.
