USB: convert ehci debug files to use debugfs instead of sysfs
We should not have multiple line files in sysfs, this moves the data to debugfs instead, like the UHCI driver. Signed-off-by: Tony Jones <tonyj@suse.de> Cc: Kay Sievers <kay.sievers@vrfy.org> Cc: David Brownell <david-b@pacbell.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
