ASoC: qcom: q6apm-dai: set flags to reflect correct operation of appl_ptr

Browse source

commit 950a4e5788 upstream.

Driver does not expect the appl_ptr to move backward and requires
explict sync. Make sure that the userspace does not do appl_ptr rewinds
by specifying the correct flags in pcm_info.

Without this patch, the result could be a forever loop as current logic assumes
that appl_ptr can only move forward.
