[PATCH] arm: dts: iot2050: Add cfg register space for ringacc and udmap

From: Jan Kiszka <jan.kiszka at siemens.com>

Recent unrelated fixes (9876ae7db6da) revealed that we were missing bits
from 2af181b53e28 in the IOT2050 dt. Add them, but only for main U-Boot.
SPL loads from QSPI only, thus cannot use DMA.
