media: staging/ipu7: Call synchronous RPM suspend in probe failure
[ Upstream commit 1433e6ccc25e9ea596683ab66e1c51f37fc7d491 ]
If firmware authentication failed during driver probe, driver call an
asynchronous API to suspend the psys device but the bus device will be
removed soon, thus runtime PM of bus device will be disabled soon, that
will cancel the suspend request, so use synchronous suspend to make
sure the runtime suspend before disabling its RPM.
IPU7 hardware has constraints that the PSYS device must be powered off
before ISYS, otherwise it will cause machine check error.
