drm/amdgpu/mes: Simplify hqd mask initialization

Browse source

"adev->mes.compute_hqd_mask[i] = adev->gfx.disable_kq ? 0xF"
is actually incorrect for MEC with 8 queues per pipe.
Let's get rid of version check and hardcode, calculate hqd
mask with number of queues per pipe and number of gfx/compute
queues kernel used.

Currently, only MEC1 is used for both kernel/user compute queue.
To enable other MEC, we need to redistribute queues per pipe and
adjust queue resource shared with kfd that needs a separate patch.
Just skip other MEC for now to avoid potential issues.

v2: Force reserved queues to 0 if kernel queue is explicitly disabled.
