This is loosely based on some initial work I did, but not to the degree
where this copyright is necessary, feel free to drop it on the next
revision.

For this to work you also need to build the DTB with labels (the -@ flag
to dtc), otherwise this board won't boot. You can add the following to
the Makefile:
DTC_FLAGS_sm8350-oneplus-lemonade := -@
DTC_FLAGS_sm8350-oneplus-lemonadep := -@
