usb: musb: fix reset issue with full speed device
TXMAXP register is not getting programmed correctly for a full speed device as can_bulk_split() have been removed by "0662481: usb: musb: disable double buffering when it's broken" patch. Adding back the case for can_bulk_split() to fix the reset message seen with a full speed stick. Signed-off-by: Ajay Kumar Gupta <ajay.gupta@ti.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
