rfkill_register was turning on bluetooth module by accident because
rfkill state was not set. The default setting was used which happened to
be turning on bluetooth.
Also remove a uncessary poweroff call.

ARM: omap4: tuna: bluetooth: set autosuspend delay to 0

The uart state is controlled by the BT_WAKE and BT_WAKE_HOST
gpios, disable autosuspend.  This prevents UART2 being stuck
on in suspend sometimes.
