[PATCH] net: 8390: ne: Fix accidentally removed RBTX4927 support

[Geert Uytterhoeven]

The configuration settings for RBTX4927 were accidentally removed,
leading to a silently broken network interface.

Re-add the missing settings to fix this.

Fixes: 8eb97ff5a4ec941d ("net: 8390: remove m32r specific bits")
Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
---
Bisected between v4.9-rc2 (doh) and v4.17-rc5.

Note to myself: I should do more boot testing on RBTX4927.
Fortunately I caught it before it ends up in a point release ;-)

Better to go on a wild bisect ride than not be able to find the
bug at all :-)

Applied, thanks.
