sparc idle: rename pm_idle to sparc_idle
(pm_idle)() is being removed from linux/pm.h because Linux does not have such a cross-architecture concept. sparc uses an idle function pointer in its architecture specific code. So we re-name sparc use of pm_idle to sparc_idle. Signed-off-by: Len Brown <len.brown@intel.com> Acked-by: David S. Miller <davem@davemloft.net> Acked-by: Sam Ravnborg <sam@ravnborg.org>
