[PATCH 2/4] drm/i915/gt: Fix SPDX license format

[Krzysztof Karas]

Hi Andi

> Header files need to declare the SPDX under /* ... */ style
All files modified in this patch series start with:
// SPDX-License-Identifier: MIT
rather than:
/* SPDX-License-Identifier: MIT */

As a note:
:~/linux/drm-tip/drivers/gpu/drm/i915$ rg "// SPDX-License-Identifier: " | wc -l
242
:~/linux/drm-tip/drivers/gpu/drm/i915$ rg "/* SPDX-License-Identifier: " | wc -l
696

are those styles interchangable or is one preferred over the
other? I am just curious seeing both are being used.

Best Regards,
Krzysztof
