[ARM] clkdev: fix clock matching
The old matching algorithm was too fuzzy, causing false positives.
For example, when asked for device D connection C1 and we only find
device D connection C2, we return that as a valid match despite the
connection names being different.
Change the algorithm such that:
An entry with a NULL ID is assumed to be a wildcard.
If an entry has a device ID, it must match
If an entry has a connection ID, it must match
However, we maintain the order of precidence while still only doing
a single pass over all entries: dev+con > dev only > con only.
