arm64: dts: qcom: msm8998: enable adreno_smmu by default
[ Upstream commit 98a0c4f2278b4d6c1c7722735c20b2247de6293f ]
15 qcom platform DTSI files define an adreno_smmu node.
msm8998 is the only one with adreno_smmu disabled by default.
There's no reason why this SMMU should be disabled by default,
it doesn't need any further configuration.
Bring msm8998 in line with the 14 other platforms.
This fixes GPU init failing with ENODEV:
msm_dpu c901000.display-controller: failed to load adreno gpu
msm_dpu c901000.display-controller: failed to bind 5000000.gpu (ops a3xx_ops): -19
Fixes: 87cd46d68aeac8 ("Configure Adreno GPU and related IOMMU")
