Commit Message

  The current design is that, for asynchronous events like link_up and
link_down firmware raises the interrupt to kernel. The previous patch
which added RPM_USX driver has a bug where it uses old csr addresses
for configuring interrupts. Which is resulting in losing interrupts
from source firmware.

This patch fixes the issue by correcting csr addresses.
