[PATCH v2] wifi: brcmfmac: add Cypress 43439 SDIO ids

[PATCH v2] wifi: brcmfmac: add Cypress 43439 SDIO ids

[Marek Vasut]

Add SDIO ids for use with the muRata 1YN (Cypress CYW43439).
The odd thing about this is that the previous 1YN populated
on M.2 card for evaluation purposes had BRCM SDIO vendor ID,
while the chip populated on real hardware has a Cypress one.
The device ID also differs between the two devices. But they
are both 43439 otherwise, so add the IDs for both.

On-device 1YN (43439), the new one, chip label reads "1YN":
```
/sys/.../mmc_host/mmc2/mmc2:0001 # cat vendor device
0x04b4
0xbd3d
```

EA M.2 evaluation board 1YN (43439), the old one, chip label reads "1YN ES1.4":
```
/sys/.../mmc_host/mmc0/mmc0:0001/# cat vendor device
0x02d0
0xa9a6
```

I added it because

Documentation/process/stable-kernel-rules.rst

L24  - New device IDs and quirks are also accepted.

So, really, up to the maintainer whether they are fine with it being 
backported to stable releases or not. I don't really mind either way.

Thanks. If I was aware of that, I had forgotten.

Yes, I completely agree.

IIUC you are here mixing Fixes and Cc tags, if you want to get a commit
to stable releases there should be "Cc: stable@...". So I'll remove the
Fixes tag and add the Cc tag, ok?
