Subject: [PATCH] amdgpu: fix warning about misplaced initializers

The navi10_ppt code contains two instances of an incorrect struct initializer:

drivers/gpu/drm/amd/amdgpu/../powerplay/navi10_ppt.c:601:33: error: suggest braces around initialization of subobject
      [-Werror,-Wmissing-braces]
        static SmuMetrics_t metrics = {0};
                                       ^
                                       {}
drivers/gpu/drm/amd/amdgpu/../powerplay/navi10_ppt.c:905:26: error: suggest braces around initialization of subobject
      [-Werror,-Wmissing-braces]
        SmuMetrics_t metrics = {0};
                                ^

Setting it to {} instead of {0} is correct and more portable here.

Fixes: ab43c4bf1cc8 ("drm/amd/powerplay: fix fan speed show error (for hwmon pwm)")
Fixes: 98e1a543c7b1 ("drm/amd/powerplay: add function get current clock freq interface for navi10")
