Subject: [PATCH] ASoC: SOF: i.MX: simplify Kconfig

From: Pierre-Louis Bossart <pierre-louis.bossart@...ux.intel.com>

Follow the Intel example and simplify the Kconfig
a) start from the end-product for 'select' chains
b) use 'depends on' to filter out configurations.
c) use snd-sof-of as a common module without any 'select'
