Subject: [PATCH] arm64: dts: qcom: msm8992-lg-bullhead: Correct memory overlap with SMEM region

A previously committed reserved memory region was overlapping with the
SMEM memory region, causing an error message in dmesg:
	OF: reserved mem: OVERLAP DETECTED!
	reserved@...0000 (0x0000000005000000--0x0000000007200000)
	overlaps with smem_region@...0000
	(0x0000000006a00000--0x0000000006c00000)
This patch splits the previous reserved memory region into two
reserved sections either side of the SMEM memory region.
