Subject: [PATCH] ARM: dts: nuvoton: Fix FIU reg definition

The current definitions have a reg-name for "memory", but no
corresponding reg space defined. These values were taken from the
NPCM7xx documentation and tested on real hardware.

Without this definition, the FIU driver does not take advantage of
direct read support.
