Subject: [PATCH v2] ASoC: qcom: sdm845: set quaternary MI2S codec DAI to
 I2S format

From: "Dr. Git" <drgitx@...il.com>

We configure the codec DAI format for primary and secondary but not the
quaternery MI2S path. Add the missing configuration to enable speaker
codecs on the quaternary MI2S like the MAX9827 found on the OnePlus 6.
