6.10-stable review patch. If anyone has any objections, please let me know.

From: Hsiao Chien Sung shawn.sung@mediatek.com
[ Upstream commit a4c9410b31cac463599898edb5111ca9bc0810bd ]
Set DRM mode configs limitation according to the hardware capabilities and pass the IGT checks as below:
- The test "graphics.IgtKms.kms_plane" requires a frame buffer with width of 4512 pixels (> 4096). - The test "graphics.IgtKms.kms_cursor_crc" checks if the cursor size is defined, and run the test with cursor size from 1x1 to 512x512.
Please notice that the test conditions may change as IGT is updated.
