jtag/adapter: move 'usb location' code in adapter.c
The configuration code for adapter parameters is spread around. Add a struct in adapter.c aimed at containing all the adapter's configuration data. Move in adapter.c the code related to configuring 'usb location' and the copyright tag. Add adapter.h to export the functions. While there: - rework the copyright and the SPDX tag; - rename the 'usb location' functions; - remove the JTAG_SRC variable in Makefile.am.
