Add register read/write operations tracing support. ftrace events helps to trace register read and write location details of memory mapped IO registers. These trace logs helps to debug un clocked access of peripherals. Bug: 169045115 Change-Id: I849bf75b84c24c8f3e9d2e8fba34a10ddcf4aaca Signed-off-by: Prasad Sodagudi <psodagud@codeaurora.org>
