WSA881x works in PDM mode so the wordlength is fixed, which also makes the only field "WordLength" in DPN_BlockCtrl1 register a read-only. Writing to this register will throw up errors with Qualcomm Controller. So use ro_blockctrl1_reg flag to mark this field as read-only so that core will not write to this register.

Hi Mark,
For some reason this patch was missed during last merge window, Other patch in this series is already in mainline. Without this patch audio is not functional on DB845c and other SDM845 based platforms.
Can you please take this for next possible rc.
Thanks, srini
