sparc: correct section of apc_no_idle

The latest mainline gives this section mismatch on sparc:

The function __devinit apc_probe() references
a variable __initdata apc_no_idle.
If apc_no_idle is only used by apc_probe then
annotate apc_no_idle with a matching annotation.

Since the commit 7e7e2f0,
apc_probe() is on __devinit so we have to correct apc_no_idle
which is referenced by this function.
