usb: gadget: add a inline function gether_bitrate()
In function ecm_bitrate(), it is not support report bit rate for super
speed plus mode, but it can use same bit rate value defined in ncm and
rndis.
Add a common inline function gether_bitrate() which report different for
all possible speeds, it can be used by ecm, ncm and rndis, also remove
old function from them.
