arm64: dts: qcom: msm8976: Split lpass region

Browse Source 
MSM8976 downstream dts define reloc region which is used by pil-tz
to load both wcnss and lpass, on mainline however we might not be
able to do it and we need separate regions(also validating dts might get
problematic if we had to put memory-region(rproc node) per device).
Luckily it seems size and entry points in firmware headers appears
to be static across multiple devices including Sony Loire platform
and Xiaomi Redmi Note 3 Pro this should let us fit in first ~17MB
Split lpass region(reloc on downstream) into two separate regions.
