Removing `reg` causes the following warning:
Warning (unit_address_vs_reg): /example-0/syscon@ff770000: node has a
unit name, but no reg or ranges property
Please let me know what the prefered solution would be here.

The rest of the document also has these blank lines, which is why I've
also kept them here. Are you sure I should remove them?

The example in this file is actually for `rockchip,rk3399-usb2phy` and
not `rockchip,rk3399-emmc-phy` which is why I haven't touched it.
Should I add to the example in `grf.yaml` ?

Please let me know if I've misunderstood anything or if there are any
other changes I should make.
