I can look into this and add the of_earlycon support for
8250_dw. It looks like it may be only a matter of hooking it up to the
setup function in 8250_early.c, which is quite straightforward.

So does it make more sense for me to do the following?
1) Drop the earlycon bootargs from ns2-svk.dts and continue the Broadcom
iProc arm64 upstreaming process with the current patch series
2) Start a separate, new patch series with OF_EARLYCON support to 8250
DW driver

Thanks,

Ray
