arm64: dts: marvell: armada-ap806: reserve PSCI area
The memory area [0x4000000-0x4200000[ is occupied by the PSCI firmware. Any attempt to access it from U-Boot leads to an immediate crash. So let's make the same memory reservation as the vendor device tree. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Stefan Roese <sr@denx.de>
