Subject: [PATCH] arm64: dts: qcom: msm8998-xperia: Enable lpass smmu

To support audio dsp functionality, enable the lpass smmu.
The firmware distributed with the MSM8998 Sony Xperia smartphones
requires us to skip resetting CB12 of this SMMU and to use CB11
as a context bank to emulate bypass streams.
