Subject: [PATCH] ARM: dts: msm: Add secure dma-buf heap support for neo

Added below secure dma-buf pool support for neo.
1. qcom,secure_lsr_lefteye
2. qcom,secure_lsr_righteye
3. qcom,secure_lsr_depth
4. qcom,secure_lsr_misc

Usecase demands contigious memory, so allocated
from HEAP_TYPE_SECURE_CARVEOUT.
