This series of patches splits generic cirrus HDA codecs and CS8490 bridge
into separate modules, adds support for multiple companion codecs connected to
CS8409, and also adds support for new DELL HW platform.

CS8409 part is not really a HDA codec, it is a HDA bridge where companion codecs
(up to 16) can be attached. With growing number of supported configurations and 
platforms, patch_cirrus is getting less and less transparent and maintainable.
So, the logical step is to separate generic Cirrus HDA codecs support 
and Cirrus HDA bridge support.

Lots of improvements to existing functionality, code clean-up and refactoring,
remove duplicated/redundant code, improve I2C functions etc.

Add support for new DELL HW platform with 2 CS42L42 codecs for front and rear jacks.
