If we reached here the reset lines will be asserted, and then the code
below touches sysc registers on a module under reset.

Do you know of any case where this would be a problem? ?Seems like it
would only affect IP blocks that have both hard reset lines and SYSCONFIG
registers, and as far as I know, we don't have any of those defined?

MMU (not yet mainlined) has both, a reset line and a sysconfig.

I have been holding the hwmod for some time, but now that
rpmsg/remoteproc is going to mainline it could make use of it along
with omap3isp, however now I need to define functions to handle the
reset lines (although I was fine with hwmod handling it).

AFAIKnew, hwmod handling the reset line was fine (IMHO), the only 2 things were:
- For the drivers to somehow make use of shutdown/enable if they
needed they hwmod under reset and out.
- The annoying: hwmod XX failed to hardreset because of the wrong
reset sequence but causing no functional issues.
