config: adjust dfll48m (usb) to match the docs

hal/documentation/usb_device_async.rst has a few things to say about the
SOF clock recovery mode currently used for usb, so honor those settings.

Additionally Footnote 1 in chapter 54.14 of the SAM D5x/E5x Family Data
Sheet restricts the fine step value.

osmo-ccid-firmware - CCID implementation (not just) for firmware

This repository contains a C-language implementation of the USB CCID (Smart Card Reader) device class. The code is written in a portable fashion and can be found in the ccid_common sub-directory.

The code can be built to run as an userspace program on Linux, implementing a USB Gadget using the FunctionFS interface. For this version, see the ccid_host subdirectory.

The CCID code can also be built into a firmware for the sysmoOCTSIM 8-slot high-performance USB smart card reader.
