[PATCH V3 0/3] Add audio support on smdk5420

[Padmavathi Venna]

Samsung has different versions of I2S introduced in different
platforms. Each version has some new support added for multichannel,
secondary fifo, s/w reset control, internal mux for rclk src clk and
tdm support. Each newly added change has a quirk. So this patch adds
all the required quirks as driver data and based on compatible string
from dtsi fetches the quirks. This also adds i2s support on exynos5420.

Changes since V2:
        - Seperated out driver side changes and dts changes in two
          patch sets.
        - Replaced samsung,s3c6410-i2s-v4 with samsung,s3c6410-i2s-multi
          for more clarity as suggested by Tomasz Figa.

Changes since V1:
        - Pass quirks as driver data and fetch the quirks based on
          compatible string from dtsi file as suggested by
          Tomasz Figa and Mark Brown
        - Make the I2S driver more flexible with respect to register
          access as suggested by Tomasz Figa and Mark Brown
        - Add 5420 support in the driver.
        - Modify the dtsi files with the corresponding compatible
          strings and removed the i2s quirks from 5250 dtsi file.
        - Updated the i2s Documentation with relevent changes and
          i2s versioning info.
        - Add i2s nodes on exynos5420.dtsi
        - Enable sound support on smdk5420

This patch set is made based on Mark Brown for-next branch on sound.git.
