Like the gxl, the Amlogic g12a and sm1 SoC families have a t9015 internal
audio DAC. On these more recent SoCs, any of the 3 TDM outputs can be
routed to the internal DAC. This routing is done by a small glue device
called 'toacodec'. This patchset adds support for it.

This was tested on the amlogic reference design g12a-u200.

Changes since v1 [0]:
 * Fixup patch 2 which was left in an intermediate state
   after rebasing, missing part of the changes.
   Thanks to Sergey Bolshakov for reporting it.
