Subject: [PATCH] xtensa: Fix unnecessary setting of xtime

xtensa supports read_persisitent_clock(), so there is no reason for
the arch specific code to be setting xtime. Setting xtime will be done
by the generic timekeeping code.

Please let me know if this is some sort of a workaround for an issue
instead of just an oversight.
