From: Vijendar Mukunda <Vijendar.Mukunda@xxxxxxx>
Added quirk DW_I2S_QUIRK_16BIT_IDX_OVERRIDE to Designware
driver. This quirk will set idx value to 1.
By setting this quirk, it will override supported format
as 16 bit resolution and bus width as 2 Bytes.

This patch is already applied to the audio tree, I'm just
including it here for completeness since it's not yet in
the drm tree.
