Subject: [PATCH] PM / OPP: -ENOSYS is applicable only to syscalls

Some of the routines have use -ENOSYS, which is supposed to be used only
for syscalls. Replace that with -EINVAL.

I am including this patch into the series and this one will be the first
patch of the series. Also, later patches will be updated to *not* use
-ENOSYS.

I will send out the series again once some sort of reviews are done.
