drm/tyr: gpu: fix GpuInfo::log model/version decoding

GpuInfo::log() was decoding GPU_ID like this:

  major = (self.gpu_id >> 16) & 0xff;
  minor = (self.gpu_id >> 8) & 0xff;
  status = self.gpu_id & 0xff;

That does not match the Mali GPU_ID layout and mixes unrelated
fields. Due to that, model detection becomes `mali-unknown` on
rk3588s which is wrong.

We can already get all the version information with a single
GpuId::from call (less code and cleaner), so this patch uses it.

Also renamed `GpuModels` fields from `major/minor` to
`arch_major/prod_major` to reflect their real meaning.

This change was tested on Orange Pi 5 (rk3588s) board and the
results are as follows:

Before this change:

$ dmesg | grep 'tyr'
[   19.698338] tyr fb000000.gpu: mali-unknown id 0xa867 major 0x67 minor 0x0 status 0x5

[   19.702493] tyr fb000000.gpu: Tyr initialized correctly.

After this change:

$ dmesg | grep 'tyr'
