OMAP2+: smartreflex: remove SR debug directory in omap_sr_remove()

Browse source 
omap_sr_probe() creates the smartreflex debug directory and its
underlying nvalue debug directory. These directories are removed in
omap_sr_remove().

Basic smartreflex functionality tested on OMAP3630 Zoom3 & OMAP4430 SDP
