10024cd73d drm/amd: Use amdgpu_ucode_* helpers for SDMA2.4 
The `amdgpu_ucode_request` helper will ensure that the return code for
missing firmware is -ENODEV so that early_init can fail.

The `amdgpu_ucode_release` helper is for symmetry on unloading.

c9ba134e05 drm/debugfs: use octal permissions instead of symbolic permissions 
Currently, debugfs functions are using symbolic macros as permission
bits, but checkpatch reinforces permission bits in the octal form, as
they are more readable and easier to understand [1]. Moreover, using
the symbolic macro S_IFREG is redundant.

Therefore, use octal permission bits in all debugfs functions.

3db9d59055 drm/i915/gt: Reset twice 
After applying an engine reset, on some platforms like Jasperlake, we
occasionally detect that the engine state is not cleared until shortly
after the resume. As we try to resume the engine with volatile internal
state, the first request fails with a spurious CS event (it looks like
it reports a lite-restore to the hung context, instead of the expected
idle->active context switch).

6d6defd421 drm/mxsfb: improve clk handling for axi clk 
Ignoring errors from devm_clk_get() is wrong. To handle not all platforms
having an axi clk use devm_clk_get_optional() instead and do proper error
handling.

Also the clk API handles NULL as a dummy clk (which is also returned by
devm_clk_get_optional() if there is no clk) so there is no need to check
for NULL before calling clk_prepare_enable() or its counter part.

If GFX11 microcode is required but not available during early init, the
firmware framebuffer will have already been released and the screen will
freeze.

Move the request for GFX11 microcode into the early_init phase
so that if it's not available, driver init will fail.

Simplifies the code so that GFX10 will get the firmware
name from `amdgpu_ucode_ip_version_decode` and then use this filename
to load microcode as part of the early_init process.

Any failures will cause the driver to fail to probe before the firmware
framebuffer has been removed.
