[sean.wang at mediatek.com]

From: Sean Wang <objelf at gmail.com>

The patchset adds the MT7921 SDIO (MT7921S) Blutooth support to btmtksdio
driver, which basically are made up of 3 parts.

PART 1: patch 1-3 to create btmtk module to rely on

These are preliminary patches for MT7921s driver to move the common
firmware download procedure and the common functions from MT7921u to btmtk
module to make MT7921u, MT7921s and other devices can share with to reduce
the unnecessary duplicated code being created.

PART 2: patch 4-8 to refactor btmtksdio prior to adding mt7921s

These are preliminary patches for MT7921s driver to refactor the current
btmtksdio to make MT7921S is able to coexist with the devices the current
driver can support with the generic code and improve the performance on
packet transmitting and receving process.

PART 3: patch 9-10 to add specific mt7921s logic

Add the specific logic regarding to mt7921s bluetooth.

The changelog from v1 to v2:
- fix the test failure reported from bluez test bot
- fix the test warning reported from kernel test robot
- rebase onto the up-to-date bluetooth-next/master 
- fix the typo from mt7961_data to mt7921_data
- improve the function btsdio_mtk_reg_read with dropping the hard coding
