adw_pci.c: Update comments describing supported chips/cards. adwcam.c: adwlib.c: adwlib.h: Handle more error return codes from the firmware. Break out the bus reset code into its own function. Usa a constant for the bus reset hold delay. Fix an interrupt race problem in adw_idle_cmd_send by incorporating the poll loop for command completion. Approved by: jkh@FreeBSDorg
