Subject: [PATCH] freedreno: Include speedbin fallback in 740 chipid to fix
 probing

The kernel exposes CHIP_ID, which consists of:

[63:48] const 0 / reserved
[47:32] speedbin (default 0xffff)
[31:0 ] actual gpu chip ID

Fix the 740 chip id to make it probe correctly.
Keep the existing entry for the downstream KGSL driver.

Fixes: cd3719be7d09 ("freedreno: Fully define a730 and a740 device properties")
