ASoC: Samsung: Add common I2S driver

The I2S controllers since S3C64XX are incremental revisions, with
a new feature added to the last one. The programming i/f doesn't
conflict between these revisions, so it is possible to have one
common driver that could manage various versions of I2S (v3, 4 & 5)
