drm/amdgpu: fix sysfs ip base addr for 64bit in standalone mode

Browse source

In standalone mode the ip_discovery sysfs tree is built from a verbatim
copy of the discovery binary taken before reg_base_init() collapses the
64bit base addresses in place. Decoding as 32bit there yields interleaved
zeros. Decode base_address_64[] in that case; keep reading the already
collapsed adev->discovery.bin as-is otherwise.
