Sysfw provides an option for requesting exclusive access for a

device from a different host will be nacked by sysfw.
Current tisci firmware and pm drivers always requests for device with
exclusive permissions set. But this is not be true for certain devices
that are expcted to be shared across different host contexts.
So add support for getting the shared or exclusive permissions from DT
and request firmware accordingly.
Gentle Ping on this series.
I can queue this up.
