I often do this aswell, apparently not all the time :-/

This message is also not seen often during booting since the driver has
this in it:

/*
* The PMIC could already be initialized by the bootloader.
* Skip initialization here in this case.
*/
if (!pwrap_readl(wrp, PWRAP_INIT_DONE2)) {
ret = pwrap_init(wrp);
if (ret) {
dev_dbg(wrp->dev, "init failed with %d\n", ret);
goto err_out2;
}
}

I first have to comment out the already initialized check to see this
message. I just rechecked, yes, the initialisation still works as
expected.
