Sean Wang 561ae1d46a Bluetooth: btmtksdio: fix resume failure
btmtksdio have to rely on MMC_PM_KEEP_POWER in pm_flags to avoid that
SDIO power is being shut off during the device is in suspend. That fixes
the SDIO command fails to access the bus after the device is resumed.

Sean Wang 4b4b2228f5 Bluetooth: btmtksdio: handle runtime pm only when sdio_func is available
Runtime pm ops is not aware the sdio_func status that is probably
being disabled by btmtksdio_close. Thus, we are only able to access the
sdio_func for the runtime pm operations only when the sdio_func is
available.

Sean Wang 26270bc189 Bluetooth: btmtksdio: move interrupt service to work
btmtksdio belongs to WIFI/BT combo chip that would serve two radios in one
sdio_irq so that we have to move interrupt service to worker to ensure ISR
as short as possible.

The worker would serve the both Tx and Rx in a batch to effectively reduce
many interrupts to the host and to avoid excessive sdio lock contention
between various context (even from WiFi driver) and help to be more
efficient to complete command/event transation.

the module is loaded too early - this should be handled from user-space

Sean Wang 9aebfd4a22 Bluetooth: mediatek: add support for MediaTek MT7663S and MT7668S SDIO devices
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.
