This fixes the lost aliases for the IOT2050 series, fixes mini PCIe card
hangs, drops an unused device node, brings runtime pinmuxing for the
Arduino connector via debugfs. Finally, it enables PRU-based Ethernet on
PG2/M.2 device variants (depends on [1]). PG1 devices still need changes
to the TI driver to enable them as well.
Changes in v2:
- dropped spidev enabling - still looking for flexible and acceptable
solution
- added some missing signed-offs

From: Su Bao Cheng <[email protected]>
Make the m.2 power control pin also available on miniPCIE variants.
This can fix some miniPCIE card hang issue, by forcing a power on reset
during boot.

Add the required nodes to enable ICSSG SR2.0 based prueth networking.
As the driver still needs to be extended for SR1.0 support, keep related
