[v4,0/3] Add support for NXP bluetooth chipsets

Message

This patch adds a driver for NXP bluetooth chipsets.

The driver is based on H4 protocol, and uses serdev APIs. It supports host
to chip power save feature, which is signalled by the host by asserting
break over UART TX lines, to put the chip into sleep state.

To support this feature, break_ctl has also been added to serdev-tty along
with a new serdev API serdev_device_break_ctl().

This driver is capable of downloading firmware into the chip over UART.

The document specifying device tree bindings for this driver is also
included in this patch series.
