usb: renesas_usbhs: Modify ep.caps.type_xxx and usb_ep_maxpacket_limit()
This patch modifies the ep.caps.type_{iso,bulk,int} setting and the second argument of usb_ep_maxpacket_limit() using the dparam.pipe_configs. In the previous code, all the type_{iso,bulk,int} were set to true. However, to avoid waste time for finding suitable pipe in usb_ep_enable(), this driver should set correct type. Also the second argument of usb_ep_maxpacket_limit() was set to 512 even if the pipe is isochronous or interrupt. So, this driver could not bind a gadget driver like the g_audio driver.
