Subject: [PATCH 2/2] sound: lpass-cpu: add module licence and description
This patch adds module licence to lpass-cpu driver, without this
patch lpass-cpu module would taint with below error:

Disabling lock debugging due to kernel taint
snd_soc_lpass_cpu: Unknown symbol regmap_write (err 0)
snd_soc_lpass_cpu: Unknown symbol devm_kmalloc (err 0)
