coresight: etm4x: Allocate and device assign 'struct etmv4_drvdata' earlier

Browse source

Allocate and device assign 'struct etmv4_drvdata' earlier during the driver
probe, ensuring that it can be retrieved in power management based runtime
callbacks if required. This will also help in dropping iomem base address
argument from the function etm4_probe() later.
