This patch series introduces a new optional device tree property
device-wakeup-gpios, which specifies the GPIO connected to BT_WAKE_IN pin of
the NXP chipset.

If this property is defined, the BTNXPUART driver uses this GPIO to put
the BT controller into sleep or wake it up, instead of the default UART
break mechanism.

The vendor command parameters HCI_NXP_WAKEUP_METHOD are configured to
use GPIO method instead of UART-break signal, to inform the chip about
this new mechanism.

Once power save feature is enabled, the driver puts the chip into power
save state by driving the GPIO high, and wakes it up by driving the GPIO
low.
