[sean.wang at mediatek.com]

From: Sean Wang <objelf at gmail.com>

The patchset adds the SDIO support to the MT7921 driver, basically are
made up of 3 parts.

PART 1: patch 1-5, 8-9 and 12-14
These are preliminary patches for mt7921s driver to refactor and reuse the
current mt7921e driver as much as possible.

PART 2: patch 6-7, 10
These are preliminary patches for mt7921s driver to refactor and reuse the
current mt7663s driver as much as possible.

PART 3: patch 11 and 15-16
These are specific patches for mt7921s driver and reset mechanism in the
same framework where mt7921e have been supported.

The patchset are built and generated against the current mt76 tree
with the tag mt76-for-kvalo-2021-10-12 to help the review and merge process
be easier.

The change list from v1 to v2
1. rework the whole driver according to the new patches added
   ("mt76: introduce __mt76_mcu_send_firmware routine"),
   ("mt76: not accounting the MCU header size in __mt76_mcu_send_firmware for mt7915/21") and
   ("mt76: sdio: move common code in mt76_sdio module")
2. drop pci_init.c and sdio_init.c by moving the related logic to pci.c and sdio.c, respectively.
3. cosmetics the patches like removing unnecessary new line, adding an extra space to fixed_map table and so on ...
4. fix typo in commit message

The change list from v2 to v3
1. rebase onto the latest mt76 branch
2. update per Lorenzo comments on v2
3. fix scheduling while atomic in mt7921_mac_sta_poll for mt7921s driver

The change list from v3 to v4
1. change the title of coverletter
2. fix the git message in patch 14
3. rebase onto the mt76-for-kvalo-2021-10-12
