Subject: [PATCH 5.13 029/127] arm64: dts: qcom: msm8992-bullhead: Fix cont_splash_mem mapping

From: Petr Vorel <petr.vorel@...il.com>

[ Upstream commit 3cb6a271f4b04f11270111638c24fa5c0b846dec ]

cont_splash_mem has different memory mapping than generic from msm8994.dtsi:

[    0.000000] cma: Found cont_splash_mem@0, memory base 0x0000000003400000, size 12 MiB, limit 0xffffffffffffffff
[    0.000000] cma: CMA: reserved 12 MiB at 0x0000000003400000 for cont_splash_mem

This fixes boot.
