drm/amd/display: fix array index out of bound error in bios parser

Browse source

[Why&How]
Firmware headers dictate that gpio_pin array only has a size of 8. The
count returned from vbios however is greater than 8.

Fix this by not using array indexing but incrementing the pointer since
gpio_pin definition in atomfirmware.h is hardcoded to size 8
