Sameer Pujar 681288f1be ASoC: tegra-alt: restructure drivers
Because of the way in which Makefile is defined for the drivers,
each driver file is getting compliled as separate *.ko module.
This results in loading of all the *.ko modules for maintaining
the functionality.

Current patch re-organises makefile and thus terga-alt structure,
 - utils/ : will provide all the helper functions,
 - machine_drivers/ : lists all the machine specific drivers we have,
 - tegra-alt/*.c : ahub module drivers, each would have a separate
   driver module,
 - include/ : all the local header files needed for driver modules

Bug 200346429
