arm64: dts: qcom: sdm845-db845c: Mark cont splash memory region as reserved
[ Upstream commit 110e70fccce4f22b53986ae797d665ffb1950aa6 ] Adding a reserved memory region for the framebuffer memory (the splash memory region set up by the bootloader). It fixes a kernel panic (arm-smmu: Unhandled context fault at this particular memory region) reported on DB845c running v5.10.y.
