USB: ehci: omap: use default interrupt threshold
The current driver reduces the interrupt threshold to 1 microframe. This was an accidental change and is not really required. The default of 8 microframes will do just fine. So change it back. Signed-off-by: Anand Gadiyar <gadiyar@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
