Add 3 debugfs entries that can be useful in debugging a variety of
issues.

bootlog - output the device bootloader log

fifo_size - output the configured dbc fifo size

queued - output how many requests are queued in the dbc fifo

Bootlog is unique to the device, where as fifo_size/queued is per-dbc.

v2:
-Use size_add() for bounds check
-Move locking into reset_bootlog()
-Clamp num dbcs supported to 256 to address a sprintf warning
