arm64: dts: qcom: msm8992-bullhead: Fix cont_splash_mem mapping

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.
