Subject: [PATCH v4 06/13] remoteproc: qcom_q6v5_mss: Add modem support on
 MSM8926

While MSM8926 being 'just' an LTE-capable variant of MSM8226 it appears
the modem setup has changed significantly, by requiring mss-supply and
not using the ext-bhs-reg.

Add a new compatible and new struct to support that.
