ARM64: dts: define reserved mapping for bootloader's splash screen

Bootloader on TM2 board enables DECON and sets it to display splash
screen. To let Linux kernel to properly initialize IOMMU and devices
during probe time, additional identity mappings are needed. This patch
adds iommu-reserved-mapping property and sets up ideantity mapping for
the whole RAM available on the board.
