Subject: [patch 0/3] xtensa generic time

Hi,

here are three patches that convert the xtensa arch code to make use
of the generic time implementation.

The first one just removes xtensa's sched_clock() in order to use the
default implementation as it is the same thing.

The second one removes the platform-specific rtc get/set callbacks,
the interface is not really feasible for the generic time
implementation.  Currently, no platform implements this callback.
Platforms that want to should implement a rtc driver and
read_persistent_clock().

The third one converts xtensa to use generic time code by implementing
ccount as a clocksource.  This lets us get rid of xtensa-specific
gtod/stod as now the generic time code is used for that.
