We added a struct tuning_addr which contains a field "present"
so that the driver can tell the firmware if we have user tuning
dataor not.

The strcut img_sw_buffer is also added. This struct has no cpu address
field and uses a handle instead so that we don't pass a cpu address
to co-processor.

If the driver depends on this patch, it needs to come before the driver.
