[v1,02/43] binman: Refactor binman_entry_find() to allow other nodes

At present we can only read from a top-level binman node entry. Refactor
this function to produce a second local function which supports reading
from any node.

This one should be static. We really should agree on a naming
convention for such internal APIs. I would prefer adding _internal
suffix, or using __ prefix
