Not sure I agree that it fits there.  The driver isn't really a
bluetooth driver -- it's really just an RFKILL interface, and some
code to toggle UART clocks on and off, plus GPIO work on a
board-specific level.  In principle, the gpios could be set and the
clocks enabled in the board files, and this driver wouldn't be
necessary to get working bluetooth (as we'd use hciattach on
/dev/ttyS*).  But then, we can't toggle it off for power saving.
Maybe a better place would be plat-omap/?  But it really is more
specific to these HTC boards, not the architecture itself.

So really, the only point of this driver is to be able to power on and
off the external bluetooth chip, which is why I submitted it as helper
code to the board files.
