rt2x00: Extend PLCP descriptor definition for rt2400pci
Extend word field definitions for the PLCP words in the TX descriptor to contain the BBP fields as well. This will remove rt2400pci_write_tx_desc() from the checkstack script. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
