Refactor the tmc-etr enable operation to make it easier to handle errors in enabling the hardware. We need to make sure that the buffer is compatible with the ETR. This patch re-arranges to make the error handling easier, by deferring the hardware enablement until all the errors are checked. This also avoids turning the CATU on/off during a sysfs read session.
