drm/panic: Fix 24bit pixel crossing page boundaries
[ Upstream commit 23437509a69476d4f896891032d62ac868731668 ]
When using page list framebuffer, and using RGB888 format, some
pixels can cross the page boundaries, and this case was not handled,
leading to writing 1 or 2 bytes on the next virtual address.
Add a check and a specific function to handle this case.
Fixes: c9ff2808790f0 ("drm/panic: Add support to scanout buffer as array of pages")
