[PATCH v2 7/7] f_sdp: Change bInterval of interrupt endpoint to 3

[Peng Fan <peng.fan@nxp.com>]

From: Sherry Sun <sherry.sun@nxp.com>

Since the USB HID limits the maximum bandwidth(3072) for interrupt
endpoint transfers, when the bInterval set to 1, we can only support 3
boards to run sdp at the same time. In order to support more boards,
change the bInterval of interrupt endpoint to 3, which will not affect
the transmission speed.
