drm/amdgpu: Replace 1-element array with flexible-array member

Browse source

One-element arrays are deprecated, and we are replacing them with
flexible array members instead. So, replace one-element array with
flexible-array member in structs _ATOM_GPIO_PIN_ASSIGNMENT,
_ATOM_DISPLAY_OBJECT_PATH, _ATOM_DISPLAY_OBJECT_PATH_TABLE,
_ATOM_OBJECT_TABLE and refactor the rest of the code accordingly.

Important to mention is that doing a build before/after this patch results
in no functional binary output differences.

This helps with the ongoing efforts to tighten the FORTIFY_SOURCE
routines on memcpy() and help us make progress towards globally
enabling -fstrict-flex-arrays=3 [1].
