ata: libata: add reset tracepoints
To follow the flow of control we should be using tracepoints, as they will tie in with the actual I/O flow and deliver a better overview about what it happening. This patch adds tracepoints for hard reset, soft reset, and postreset and adds them in the libata-eh control flow. With that we can drop the reset DPRINTK calls in the various drivers.
