[PATCH] arm64: dts: qcom: msm8998: enable adreno_smmu

[Marc Gonzalez]

Right now, GPU init fails:

[    3.204009] msm_dpu c901000.display-controller: adev bind failed: -19

adreno_smmu is required, so it must be enabled.

[    3.220381] msm_dpu c901000.display-controller: bound 5000000.gpu (ops a3xx_ops)
[    3.235503] [drm:dpu_kms_hw_init:1053] dpu hardware revision:0x30000000
