Remove querying for serial-number node from vc fdt, since it's not
guaranteed to always be there (older firmwares dont provide it).
Instead, retrieve board's serial number via the mbox api.

Rename 'rpi_set_usbethaddr' and 'rpi_get_usbethaddr' to more generic
'rpi_set_ethaddr' and 'rpi_get_ethaddr', since they can also be used
to obtain factory assigned mac address on bcm2711 (rpi4), which uses
bcmgenet nic instead of usb ethernet nic.

This series focuses mainly on init handling of rpi board variants.
Init of ethernet, usb and leds for known variants is generalized and
serial number and machin-id support is added. This series also allows
bcmgenet ethernet driver to use the hw-assigned mac address on bcm2711
based boards.

Fixes an issue where the driver in case of NACK error would not properly
terminate the tranfer, resulting in BSC not sending the STOP condition
until just before the next xfer.

I had problems getting USB working on my Raspberry Pi 3B+. I tracked
the problem down to the dwc2 driver failing in its probe function
due to CONFIG_GENERIC_PHY not enabled. I fixed the phy dependency
in dwc2 and also enabled phy core in rpi_defconfig.
Daniel Brát (2):
usb: dwc2: Make having
on due to it being filled with garbage data.
The offset by which to convert the address back can vary by device,
so the value is read from devicetree 'dma-ranges' for somewhat portable
operation.
This fix was tested on Raspberry PI B+ and Raspberry PI 3B+.
