usb: introduce usb_ep_type_string() function
In some places, the code prints a human-readable USB endpoint transfer type (e.g. "bulk"). This involves a switch statement sometimes wrapped around in ({ ... }) block leading to code repetition. To make this scenario easier, here introduces usb_ep_type_string() function, which returns a human-readable name of provided endpoint type. It also changes a few places switch was used to use this new function. Signed-off-by: Chunfeng Yun <chunfeng.yun@mediatek.com> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
