xhci: dbc: Rename xhci_dbc_init and xhci_dbc_exit

These names give the impression the functions are related to
module init calls, but are in fact creating and removing the dbc
fake device

Rename them to xhci_create_dbc_dev() and xhci_remove_dbc_dev().

We will need the _init and _exit names for actual dbc module init
and exit calls.

No functional changes
