usb: Cleanup headers

Let's split the usb headers in 3 different parts, instead of having
usb_descriptor.h pull in usb_hw.h and usb_api.h.

 - usb_api.h: EC functions related to usb (e.g. connect/disconnect)
 - usb_descriptor.h: common USB names and structures
 - usb_hw.h: Functions required for interactive with EC's USB HW

BRANCH=none
BUG=b:35587171
TEST=make buildall -j
