This patch removes the custom printk macro dprintk and replaces most of
the calls made to it by dev_dbg. pr_debug was used when the calling
function did not provide the appropiate device variable.

This patch removes the custom printk macros dprintk, zilog_notify,
zilog_error, and zilog_info. All the calls to these macros were
replaced by dev_dbg, dev_notice, dev_err, and dev_info respectively
whenever possible. There were cases in which pr_debug, pr_notice,
pr_err and pr_info were used. It was when the calling function did
not provide an appropiate dev variable.
Applying this patch will trigger the out of memory checkpatch warning
for two lines. It will be fixed in a separate patch.

'timeval' is used to print timestamps in seconds and millisecond.
32-bit systems using 'struct timeval' will break in the year 2038,
So we have to replace that code with more appropriate types.
This patch changes the android driver to use timespec64.
Since this is a staging driver and the output is only used for a
debugfs file, it is fine to slightly change the output and
use nanoseconds instead. ktime_to_timespec64, is used which will return
seconds and nanoseconds.
