USB: typec: fusb302: create debugfs subdir for the driver

Browse Source 
The single debugfs file for this driver really is a log file, so make a
subdir and call it "log" to make it obvious this is what it is for.
This makes cleanup simpler as we just remove the whole directory, no
need to handle individual files anymore.
