sparc idle: rename pm_idle to sparc_idle
Browse files Browse the repository at this point in the history
(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.
