drm/amd/amdgpu: Add GPIO resources required for amdisp

Browse Source 
ISP is a child device to GFX, and its device specific information
is not available in ACPI. Adding the 2 GPIO resources required for
ISP_v4_1_1 in amdgpu_isp driver.

- GPIO 0 to allow sensor driver to enable and disable sensor module.
- GPIO 85 to allow ISP driver to enable and disable ISP RGB streaming mode.
