drm/msm/a6xx: Fix the bogus protect error on X2-85
Update the X2-85 gpu's register protect count configuration with the correct count_max value to avoid blocking the entire MMIO region from the UMD. Protect configurations are a bit complicated on A8xx. There are 2 set of protect registers with different counts: Global and Pipe-specific. The last-span-unbound feature is available only on the Pipe-specific protect registers. Due to this, we cannot use the BUILD_BUG sanity check for A8x protect configurations, so remove the A840 entry from there.
