This adds the support of enabling MT7663S and MT7668S SDIO-based
Bluetooth function.
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.

At the moment we only support ACPI enumeration for serial port attached

This commit adds a dependency on ACPI to the BT_HCIUART_RTL configuration
option, fixing the following warning when ACPI is not enabled:

With patch 279c936153 the btuart_cs driver has been deprecated in
favor of serial_cs + hci_uart combination.
static struct pcmcia_device_id btuart_ids[] = {
/* don't use this driver. Use serial_cs + hci_uart instead */

Intead of keeping it around, just remove it since it is not even
assigned to any PCMCIA identifiers anymore.

When adding the alignment and padding support for H:4 packet processing
for the Nokia driver, it broke the h4_recv_buf usage within bpa10x

The HCILL or eHCILL protocol from TI is actually an H:4 protocol with a
few extra events and thus can also use the h4_recv_buf helper. Instead
of open coding the same funtionality add the extra events to the packet
description table and use h4_recv_buf.

The linkage between the bluetooth driver and the wireless
driver is not defined properly, leading to build problems
such as:
warning: (BT_HCIRSI) selects RSI_COEX which has unmet direct dependencies (NETDEVICES && WLAN && WLAN_VENDOR_RSI && BT_HCIRSI && RSI_91X)
drivers/net/wireless/rsi/rsi_91x_main.o: In function `rsi_read_pkt':
(.text+0x205): undefined reference to `rsi_bt_ops'
As the dependency is actually the reverse (RSI_91X uses
the BT_RSI driver, not the other way round), this changes
the dependency to match, and enables the bluetooth driver
from the RSI_COEX symbol.

Commit 27378f4c1b ("Bluetooth: Avoid WARN splat due to missing
GPIOLIB") amended Kconfig to select GPIOLIB if BT_HCIUART_NOKIA,
BT_HCIUART_INTEL or BT_HCIUART_BCM is enabled since all three drivers
require it to function.
The diagnosis was correct but the treatment was not. As stated in
Documentation/gpio/consumer.txt:
Guidelines for GPIOs consumers
==============================
Drivers that can't work without standard GPIO calls should have
Kconfig entries that depend on GPIOLIB.
^^^^^^^^^
Fix it.

We could call gpiod_to_irq() only if IS_ENABLED(CONFIG_GPIOLIB) but
without GPIOLIB, the driver's power saving features can't be used,

as well.
