virtio_bt: Fix alignment in configuration struct
The current version of the configuration structure has unaligned
16-bit fields, but according to the specification [1], access to
the configuration space must be aligned.
Add a second, aligned version of the configuration structure
and a new feature bit indicating that this version is being used.
