freedreno: Include speedbin fallback in 730 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 730 chip id to make it probe correctly.
Keep the existing entry for the downstream KGSL driver.

This is essentially the same as Commit 6067aba9e6 ("freedreno: Include
speedbin fallback in 740 chipid to fix probing"), except for the older
core.

Fixes: cd3719be7d ("freedreno: Fully define a730 and a740 device properties")
