uboot-kirkwood: fix ethernet and usb

Before 2019.01 version was introduced patch, which changes cache
routines: 93b283d4 ("ARM: CPU: arm926ejs: Consolidate cache
routines to common file"). Unfortunately that patch make ethernet
and usb in kirkwood broken.

This patch backport commit 599f7aa5 ("ARM: kirkwood: disable dcache
for Kirkwood boards"), which are fix for that problem.

Fixes: dc08514e6d ("uboot-kirkwood: update to 2019.01")
Run tested: pogoplugv4

+Subject: [PATCH] ARM: kirkwood: disable dcache for Kirkwood boards
+
+Prior to commit 93b283d49f93 ("ARM: CPU: arm926ejs: Consolidate cache
+routines to common file") the kirkwood boards didn't have and dcache
+support. The network and usb drivers rely on this. Set
+CONFIG_SYS_DCACHE_OFF in the Kirkwood specific config.h.
