[PATCH] sparc idle: rename pm_idle to sparc_idle

[Len Brown]

(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.

Maybe some day, SPARC will cut over to cpuidle...
