Subject: drm/amdgpu: Remove the redundant code of psp bootloader functions
Git-commit: fd5256cbe19609bfff0cc51e9d999a46020719da
Patch-mainline: v5.17-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
The psp bootloader functions code of psp_v13_0.c had been
optimized before. According the code style of psp_v13_0.c
to remove the redundant code of psp_v11_0.c.
