Use kernel cmdline option 'usbcore.authorized_default=2' to lock all
external/user-visible USB ports by default.
The kernel distinguishes internal vs external USB ports using ACPI
methods (_UPC and _PLD) on x86/x86_64 systems. On ACPI systems, ports
marked as non-visible but connectable are considered internal (e.g.,
hard-wired USB-to-Ethernet adapters) and are automatically authorized,
while user-visible external ports require manual authorization.
However, on device tree systems the kernel lacks a standard mechanism
for identifying internal ports. The 'authorized_default=2' setting falls
back to requiring authorization for all devices on these platforms,
We list user-accessible USB ports in the device tree ('usb-ports' and
'usb-port-names'), with unlisted ports being implicitly internal and
managed separately.

The defconfigs for all architectures other than x86_64 has this
enabled, so align it with the rest.
This has no on-target impact, but it enables us to attach to a live VM
instance and debug it, or do offline debugging like resolving stack
trace lines from oops messages to source locations.
From https://en.wikipedia.org/wiki/exFAT:
... a file system optimized for flash memory such as USB flash
drives and SD cards.
... has been adopted by the SD Association as the default file
system for SDXC and SDUC cards larger than 32 GB.
The exfatprogs is also a default installed package on most modern
distros, compared to dosfstools (mkfs.vfat) which is not.

A long standing internal debate comes to its logical conclusion. Arch
naming should follow GCC. The "native /etc" has also found a better
name: classic!
README and GitHub action has been updated accordingly.
