[ Upstream commit 9d3afcb7b9f950b9b7c58ceeeb9e71f3476e69ed ]

Current MES GFX mask prevents FW to enable oversubscription. This patch
does the following:
- Fixes the mask values and adds a description for the same
- Removes the central mask setup and makes it IP specific, as it would
  be different when the number of pipes and queues are different.

v2: squash in fix from Shashank

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree
over and remove the historical wrapper inlines.

Conversion was done with coccinelle plus manual fixups where necessary.

<title>drm/amdgpu: use GFP_NOWAIT for memory allocations</title>

In the critical submission path memory allocations can't wait for
reclaim since that can potentially wait for submissions to finish.

Finally clean that up and mark most memory allocations in the critical
path with GFP_NOWAIT. The only exception left is the dma_fence_array()
used when no VMID is available, but that will be cleaned up later on.

<title>drm/amd: Add the capability to mark certain firmware as "required"</title>

Some of the firmware that is loaded by amdgpu is not actually required.
For example the ISP firmware on some SoCs is optional, and if it's not
present the ISP IP block just won't be initialized.

The firmware loader core however will show a warning when this happens
like this:
```
Direct firmware load for amdgpu/isp_4_1_0.bin failed with error -2
```

To avoid confusion for non-required firmware, adjust the amd-ucode helper
to take an extra argument indicating if the firmware is required or
optional.

On optional firmware use firmware_request_nowarn() instead of
request_firmware() to avoid the warnings.
