Reviewer's Guide by Sourcery

This PR adds two key configuration updates: enabling compressed firmware loading so that radeon/amdgpu drivers can be loaded as modules during boot, and activating Loongson DRM support for the 7A1000 chipset. The changes are implemented by updating the deepin_loongson3_desktop_defconfig file to toggle the respective flags.

No diagrams generated as the changes look simple and do not need a visual representation.
