regulator: core: Don't spew backtraces on duplicate sysfs
We don't consider a failure to add the sysfs node as a problem, so use sysfs_create_link_nowarn() so that we don't print a backtrace when duplicated files exist. Also, downgrade the printk message to a debug statement so that we're quiet here. This allows multiple drivers to request a CPU's regulator so that CPUfreq and AVSish drivers can coexist.
