[PATCH 1/2] arm64: dts: qcom: msm8992-bullhead: Remove PSCI

[Petr Vorel]

Bullhead firmware obviously doesn't support PSCI as it fails to boot
with this definition.

Fixes: 329e16d5f8fc ("arm64: dts: qcom: msm8992: Add PSCI support.")

[PATCH 2/2] arm64: dts: qcom: msm8992-bullhead: Fix cont_splash_mem mapping

[Petr Vorel]

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.

Fixes: 976d321f32dc ("arm64: dts: qcom: msm8992: Make the DT an overlay
on top of 8994")
