Exynos5420 added support for I2S TDM mode. For this, there are some
register changes in the I2S controller. This patch adds the relevant
register changes to support I2S in normal mode. This patch adds a
quirk for TDM mode and if TDM mode is present all the relevent changes
will be applied.

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 and internal mux for rclk src clk.
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.
