drm/amd: Refactor find_system_memory()

Browse source

find_system_memory() pulls out two fields from an SMBIOS type 17
device and sets them on KFD devices. The data offsets are counted
to find interesting data.

Instead use a struct representation to access the members and pull
out the two specific fields.

No intended functional changes.
