ASoC: Updates for v4.4

A first batch of updates targetted at v4.4.  There are no substantial
 core fixes here, the biggest block of changes is updates to the rcar
 drivers and the addition of a CODEC driver for the AK4613.

For snd_soc_of_xlate_tdm_slot_mask(), the tx and rx masks will use a 1 bit
for an active slot as default, and the default active bits are at the LSB of
the masks.
The explicit masks are given as array of integers, where the first
number presents bit-0 (LSB), second presents bit-1, etc. Any non zero
number is considered 1 and 0 is 0. snd_soc_of_xlate_tdm_slot_mask()
does not do anything, if either mask is set non zero value.
