dcd(samd): implement iso alloc/activate (were stubs returning false)

2026-07-03T11:01:45Z

dcd_edpt_iso_alloc/activate were unimplemented stubs. Since samd is an ISO_ALLOC port, the stack routes ISO endpoints through them, so every ISO endpoint open failed: SET_CONFIGURATION with an ISO endpoint returned -EPIPE (can't set config) and audio SET_INTERFACE(alt=1) stalled at usbd_edpt_iso_activate(). This was misdiagnosed as a samd51 hardware ISO limitation; it is not. Implement them mirroring dcd_edpt_open()'s per-direction setup: iso_alloc fixes the endpoint bank SIZE bucket for the largest packet size (persists across altsettings); iso_activate sets EPTYPE=ISO, clears stall + data toggle, enables the transfer-complete interrupt. metro_m4_express now passes the full usbtest battery 30/30 (was: SET_CONFIG failed), including ISO 15/16/22/23.

* license: use SPDX identifiers for src/ headers Replace the full ~20-line MIT license boilerplate on every src/ file with a two-line SPDX tag (SPDX-FileCopyrightText + SPDX-License-Identifier), following the REUSE convention used by CircuitPython and the Linux kernel. Removes ~3500 lines of duplicated boilerplate.

make TUP_DCD_EDPT_ISO_ALLOC i.e dcd_edpt_iso_alloc()/dcd_edpt_iso_activate() as default driver implementation. dcd_edpt_close() is deprecated and will be removed from all driver in the future.
