tegra bluesleep: Bluetooth active power management driver
A new driver is implemented to actively manage the bluetooth module

Two signals (GPIOs) are used to manage the power events.
BT_WAKE : signal from HOST to BT chip to intimate BT chip can sleep.
HOST_WAKE: signal from BT chip to HOST to intimate HOST should wakeup/
activate the transport modules required for BT communication.
