[PATCH] drm/amdgpu: fix S0ix handling when the CONFIG_AMD_PMC=m

[Liang, Prike]

Just find out the config variable is formed by the header_print_symbol() in the confdata.c and also can double confirm the variable config set value in the include/generated/autoconf.h. Maybe we can set the  AMD_PMC to 'y' by default in the platform Kconfig.

Thanks,
Prike
