Boris Brezillon dad53edc9c pan/layout: Relax alignment constraints on pre-v7 for imports of linear/u-tiled
Commit f64a7c1506 ("pan/layout: Check the wsi_layout consistency in
wsi_row_pitch_to_row_stride()") introduced stricter alignments on pre-v7
for linear/tiled imports. It turns out alignment constraints on pre-v7 are
weaker than they are on v7+, and this got lost in the refactoring.

Let's fix linear_or_tiled_row_align_req() helper so we can import images
that don't have their base address/row_pitch aligned on a cacheline, and
only cacheline alignment for images we create ourselves.

Also add unittests to make sure we don't regress that in the future.
With this being tested, we can also use
pan_linear_or_tiled_row_align_req() in offset_align_for_mod()
(test-layout.cpp) instead of open-coding it.

Fixes: f64a7c1506 ("pan/layout: Check the wsi_layout consistency in wsi_row_pitch_to_row_stride()")
Fixes: 916f75a2a6 ("pan/layout: Test WSI import behavior on all supported format/mods")
