soc/amd/common/block/lpc/lpc: simplify index handling in read resources
Now that we don't need to find a specific resource in the set resources
function any more, there's no need to use hard-coded indices for the
fixed resources. Instead use an index variable that gets incremented
after each fixed resource got added. The index now starts at 0 instead
of at 1, but now the only requirement is that those indices are unique.
