arm64: dts: mediatek: mt8195-demo: update and reorder reserved memory regions
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.
Cc: stable@vger.kernel.org # 6.1, 6.4, 6.5
Fixes: e4a417520101 ("arm64: dts: mediatek: mt8195-demo: fix the memory size of node secmon")
