It makes the code clearer to separate the bus implementation
from the devices one.
Replace ADB_DPRINTF() with trace events (and adding new ones in adb-kbd.c).
Some minor changes to make checkpatch.pl happy.
Signed-off-by: Laurent Vivier <laur...@vivier.eu>

v2: move internal declarations to adb-internal.h
replace ADB_DPRINTF() with trace event.
