What?  No, no no.

You must not use pa() on immap addresses.  All you did was convert
a proper address to some bogus one, you are writing over some other
part of memory that is eventually going to cause a failure.  The immap
addresses are identity mapped virtual to physical.

There isn't any performance problem  with this driver if your hardware
is working properly.  I cant' believe this change would have done
anything except eventually causing the system to fail.

What kernel are you using?

Thanks.
