i965: Add extra-alignment for non-msrt fast color clear for all hw (v2)

i965: Add extra-alignment for non-msrt fast color clear for all hw (v2)

The BSpec states that the aligment for the non-msrt clear rectangle must
be doubled; the BSpec does not restricit the workaround to specific
hardware.

Commit 9a1a67b applied the workaround to Haswell GT3.  Commit 8b659ce
expanded the workaround to all Haswell variants. This commit expands it
to all hardware.

No Piglit regressions on Ivybridge 0x0166. No fixes either.

I know no Ivybridge nor Baytrail bug related to this workaround.
However, the BSpec says the extra alignment is required, so let's do it.

v2: Apply to all hardware, not just gen7.
