Not sure since it is an early stage and scheduler might not work as
expected. Conversions to iopoll.h macros bitten us a few times already.

Except _atomic does not use scheduler :).

Sorry for a bit misleading comment, but I chased it down, so this what
I had in mind when commenting:
be24c6a71ecf ("soc: qcom: rpmh-rsc: Don't use ktime for timeout in
write_tcs_reg_sync()")

...and this one (specifically for early stages)

c4d936efa46d ("Revert "usb: early: convert to readl_poll_timeout_atomic()"")

OK, makes sense.

thanks for pointers,
