[PATCH v2] drm/amd/display: fix struct init in update_bounding_box

[Raul E Rangel]

dcn20_resource.c:2636:9: error: missing braces around initializer [-Werror=missing-braces]
  struct _vcs_dpi_voltage_scaling_st calculated_states[MAX_CLOCK_LIMIT_STATES] = {0};
         ^

So apparently `{}` is a gcc extension. The C standard requires at least
one expression. So {{0}} is correct. I got a lint error about {{0}}
needing a space, so i use `{ {0} }`.

Changes in v2:
- Use { {0} } instead of {}
