rtc: Fix RTC PIE frequency limit
BugLink: http://bugs.launchpad.net/bugs/868628
commit 938f97bcf1bdd1b681d5d14d1d7117a2e22d4434 upstream.
Thomas earlier submitted a fix to limit the RTC PIE freq, but
picked 5000Hz out of the air. Willy noticed that we should
instead use the 8192Hz max from the rtc man documentation.
