This patchset is based on Florian's initial PROTO driver: https://lkml.org/lkml/2013/5/22/342

My changes made the driver more generic, so that we could connect other I2S CPU DAIs, by using device-tree.

Tested with sama5d2 I2S driver.

Changes in v2: - removed unnecessary code that added constraints for the fixed SYSLK; - fixed errors reported by kbuild; - adjusted "mikroe" in vendor prefixes; - updated description in Kconfig;
