2024–02–28: Support for WiFi on QuartzPro64

So I got an itch to look at the AP6275P PCIe module again, which is present on QuartzPro64 board from Pine64.

And I managed to get it working with upstream bcrmfmac driver and some small patches

The only a bit more complicated thing to figure out was how to tie DT node to a PCIe device connected to a PCIe port, because this is not very well documented and invloves conjuring quite a few magic numbers, as can be seen in the above patch.

Then I had to add a way to enable 32kHz clock that is generated by the real-time clock chip and necessary for WiFi to function.

The result is that the chip now works:
