[rfc] separate sharpsl_pm initialization from sysfs code

[Pavel Machek <pavel@ucw.cz>]

Hi!

On collie, battery sensing code is not on platform bus -- it is on
ucb1x00. Is this acceptable way to make sharpsl_pm useful for collie?
It separates code that is bus-independent, so collie can call only
code it needs.
