[alsa-devel] [PATCH]: ARM DaVinci ASoC: Fix module unload error

[chaithrika at ti.com]

From: Chaithrika U S <chaithrika at ti.com>

Fix for the error when the audio module is unloaded.
On unregistering the platform_device, platform_device_release will free the 
platform data.If platform data is static the kernel panics when it is freed.
Instead use the platform device helper function to add data.

This change has been tested on DM644x EVM.
