[PATCH 0/2] fix Lager earlycon

[Ulrich Hecht]

Hi!

This makes earlycon work on the Lager board:

1. It amends the SCI earlycon patch by Sato-san slightly to preserve the
other bits in SCSCR when asserting RE and TE.

2. It switches the serial console back to SCIF0, because that's what the
boot loader uses, and we rely on it to set up the port for us...

I have yet to check to what extent other boards/SoCs are affected by this.
