Subject: [RFC PATCH 1/3] ASoC: Add platforms directory

Platform ASoC drivers are a lot like ASoC CODEC drivers in that they
both are independent pieces of a sound device, or "machine". Platform
drivers should be free of CODEC specifics and visa-versa. Both are then
used by the the "machine" driver to form the complete sound device.
This forms a hierarchy that makes it natural to group platform drivers
into their own directory, much like we group CODEC drivers already.

With this change, we will leave machine drivers in the top-level ASoC
directory and have CODECs and Platforms below. The machine drivers may
also be moved at some point into a grouping directory to further
enforce the logical separation intended by the ASoC framework.

Create the initial directory, Kconfig, and Makefile here.
