The class kind is only necessary to lookup the chardev name in
qmp_chardev_add() after calling qemu_chr_new_from_opts(). However,
qemu_chr_new_from_opts() can be changed to use a non-qmp function using
the chardev class typename. Introduce qemu_chardev_add() to be called
from qemu_chr_new_from_opts() and remove the class chardev kind field.
