arm64: dts: mediatek: mt8195-demo: update and reorder reserved memory regions

Browse source 
commit 6cd2a30b96 upstream.

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.
