ASoC: Blackfin: standardize machine driver names

Some machine drivers were using "bf5xx-", others were using "bf5xx_",
while others were using "bfin-".  Further, some were using the same
name in the transport layer which makes it hard to use different codecs
at the same time.  So standardize all of them to "bfin-" and make sure
they are name spaced according to their driver name.
