There are current places in the code, and there will be more in the
future, which iterate the forcewake domains to find out which ones
are currently active.
To save them from doing this iteration, we can cheaply keep a mask
of active domains in dev_priv->uncore.fw_domains_active.
This has no cost in terms of object size, even manages to shrink it
overall by 368 bytes on my config.

Looks solid and should not run afoul of the games played during reset or
suspend.

Thanks!
Praveen, you can see if this patch would help for your decoupled MMIO
patches, and if you like it you can incrorporate it in your series if
you want?
Thanks for the patch Tvrtko! I can definitely use it :)
Regards,
Tvrtko
