ASoC: wm_adsp: Don't generate kcontrols without READ flags

Browse Source 
[ Upstream commit 3ae7359c0e ]

User space always expects to be able to read ALSA controls, so ensure
no kcontrols are generated without an appropriate READ flag. In the case
of a read of such a control zeros will be returned.
