Bluetooth: btusb: Configure altsetting for HCI_USER_CHANNEL

Automatically configure the altsetting for HCI_USER_CHANNEL when a SCO
is connected.

The motivation is to enable the HCI_USER_CHANNEL user to send out SCO
data through USB Bluetooth chips, which is mainly used for bidirectional
audio transfer (voice call). This was not capable because:

- Per Bluetooth Core Spec v5, Vol 4, Part B, 2.1, the corresponding
alternate setting should be set based on the air mode in order to
transfer SCO data, but
- The Linux Bluetooth HCI_USER_CHANNEL exposes the Bluetooth Host
Controller Interface to the user space, which is something above the
USB layer. The user space is not able to configure the USB alt while
keeping the channel open.

This patch intercepts the HCI_EV_SYNC_CONN_COMPLETE packets in btusb,
extracts the air mode, and configures the alt setting in btusb.

This patch is tested on ChromeOS devices. The USB Bluetooth models
(CVSD, TRANS alt3 and alt6) could work without a customized kernel.

Bluetooth: hci_uart: Add support for Amlogic HCI UART

Add a new HCI protocol HCI_UART_AML for the Amlogic Bluetooth
controller. It works on the standard H4 protocol via a 4-wire UART
interface, with baud rates up to 4 Mbps.

The controller supports two types of commands: the TCI commands and the
vendor command. The former is for initial setup including setting baud
rates, downloading fw, starting chip and etc, while the latter is for
dumping firmware versions and setting public address after firmware
updates and normal startup.

It was verified on board of T602 (S905X4 + W265S2).

Bluetooth: NXP: Add protocol support for NXP Bluetooth chipsets

This adds a driver based on serdev driver for the NXP BT serial protocol
based on running H:4, which can enable the built-in Bluetooth device
inside an NXP BT chip.

This driver has Power Save feature that will put the chip into sleep state
whenever there is no activity for 2000ms, and will be woken up when any
activity is to be initiated over UART.

This driver enables the power save feature by default by sending the vendor
specific commands to the chip during setup.

During setup, the driver checks if a FW is already running on the chip
by waiting for the bootloader signature, and downloads device specific FW
file into the chip over UART if bootloader signature is received..

There are quite many differences between MT766[3,8]S and standard
Bluetooth SDIO devices such as Type-A and Type-B devices. For example,
MT766[3,8]S have its own SDIO registers layout, definition, SDIO packet
format, and the specific flow should be programmed on them to complete
the device initialization and low power control and so on.

Currently, there are many independent programming sequences from the
transport which are exactly the same as the ones in btusb.c about MediaTek
support [1] and btmtkuart.c. We can try to split the transport independent
Bluetooth setups on the advance, place them into the common files and allow
varous transport drivers to reuse them in the future.
