tegra bluesleep: Bluetooth active power management driver

A new driver is implemented to actively manage the bluetooth module
power. bluesleep also tries to manage the power of the transport used.

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.
