* Reduce the keyboard queue size from 64 to 32, which is more than
enough even for real-time games with multiple key presses.
* Pack the driver_event_t structure of the keyboard driver to make it 4
bytes rather than 6 bytes. Combined with the previous item, this saves
256 bytes off the BSS section (which is 3% of the SH3's static RAM).
* As part of a debugging attempt, updated the watchdog delay code in
iokbd_delay() to make it usable in the current version of gint.
* Restored port registers more aggressively in iokbd_row().
