Fabio Estevam bae35992af ASoC: fsl: imx-audmux: Do not call imx_audmux_parse_dt_defaults() on non-dt kernel 
Booting a mx51babbage board with a non-dt kernel leads to the following crash:

Unable to handle kernel NULL pointer dereference at virtual address 0000001c
pgd = 80004000
[0000001c] *pgd=00000000

This is caused by commit 8548a464b9 (ASoC: imx-audmux: Read default
configuration from devicetree).

In order to fix this, add a check for 'of_id' so that
imx_audmux_parse_dt_defaults() only gets called when a dt kernel is running.
