Chris Wilson 1f767e02d6 drm/i915: HWS must be in the mappable region for g33 
On g33, the documentation states

"HWS_PGA:
 Format = Bits 28:12 of graphics memory address (bits 31:29 MBZ)."

which translates to that the address of the HWS must be below 256MiB,
which is conveniently the mappable aperture.

This also appears to be true (but not documented as so) for gen4 and
gen5. To generalise we force it into the low mappable region for all
non-LLC platforms. If we locate the HWS at the top of the GTT the
machine will hard hang during boot (fails on pnv, gm45, ilk and byt,
but works on snb, ivb, hsw).

v2: Add comments to explain why use PIN_MAPPABLE even though we have
    no intention of mapping the object. (Ville)
