There are formats which bpp are not aligned to a power-of-two and
that can cause problems in the checks we do.
The cacheline size was a requirement for using the BLT engine, which
we don't use anymore except for a few things on old HW, so we drop it.
Fixes CTS's CL#3500 test:
dEQP-VK.api.image_clearing.core.clear_color_image.2d.linear.single_layer.r8g8b8_unorm
