Until now, the arygon and pn53x_usb were unconditionally enabled, and
there were no options to choose other drivers. Therefore, we had
sub-options for each individual driver, keeping arygon and pn53x_usb
enabled by default to preserve backward compatibility.
Also, due to this, the BR2_TOOLCHAIN_HAS_THREADS dependency on the
libnfc package is no longer needed, and is only needed for some of the
sub-options.

[Thomas:
- drop the default ""
- remove the top-level HAS_THREADS dependency, and move it down to
the sub-options that need it
- improve commit log]
