xen/usb: Constify struct hc_driver
'struct hc_driver' is not modified in this driver.
Constifying this structure moves some data to a read-only section, so
increases overall security, especially when the structure holds some

Before:
======
text data bss dec hex filename

After:
=====
text data bss dec hex filename
