[PATCH] ARM: dts: nuvoton: Fix flash layout

[Anton Kachalov]

Hello, Tomer.

Seems like Nuvoton's u-boot expects the uboot-env at different address
comparing to openbmc-flash-layout.dtsi:

https://github.com/Nuvoton-Israel/u-boot/blob/npcm7xx-v2019.01/include/configs/poleg.h#L30

Vs.

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/arm/boot/dts/openbmc-flash-layout.dtsi#n13

The change is more about making partitions naming the same as expected by
OpenBMC.
