Subject: usb: r8a66597-hcd: decrease timeout

From: Chris Brandt <[email protected]>

commit dd14a3e9b92ac6f0918054f9e3477438760a4fa6 upstream.

The timeout for BULK packets was 300ms which is a long time if other endpoints or devices are waiting for their turn. Changing it to 50ms greatly increased the overall performance for multi-endpoint devices.
