Andrew Banman 1b17c6df85 x86/platform/uv/BAU: Fix HUB errors by remove initial write to sw-ack register
Writing to the software acknowledge clear register when there are no
pending messages causes a HUB error to assert. The original intent of this
write was to clear the pending bits before start of operation, but this is
an incorrect method and has been determined to be unnecessary.
