[PATCH 2/4] arm64: dts: mediatek: mt8195-demo: update and reorder reserved memory regions

[Macpaul Lin]

The dts file of the MediaTek MT8195 demo board has been updated to include
new reserved memory regions.
These reserved memory regions are:
 - SCP
 - VPU,
 - Sound DMA
 - APU.

These regions are defined with the "shared-dma-pool" compatible property.
In addition, the existing reserved memory regions have been reordered by
their addresses to improve readability and maintainability of the DTS
file.
