Subject: [PATCH] drm/amdgpu/gmc: fix compiler errors [-Werror,-Wmissing-braces]
Initializing structures with { } is known to be problematic since
it doesn't necessararily initializes all bytes, in case of padding,
causing random failures when structures are memcmp().
This patch fixes the structure initialisation compiler error by memsetting
the entire structure elements instead of only the first one.
