[PATCH 1/2] tests/amdgpu: Fix typos and grammar in test files

[Alex Hung <alex.hung@amd.com>]

Fix various typos and grammar errors across multiple AMDGPU
test files:
- amd_abm: "amdpgu" -> "amdgpu", fix grammar in comment
- amd_assr: add missing article, remove trailing spaces
- amd_color: "amdpgu" -> "amdgpu", "liner" -> "linear",
  fix incorrect "degamma" comment in regamma function
- amd_plane: "backgroud" -> "background",
  "overley" -> "overlay", "beacause" -> "because",
  fix wrong size notation and misleading comment
- amd_vrr_range: "gange" -> "range" in function name
