Subject: [PATCH 5.13 033/127] arm64: dts: qcom: sdm845-oneplus: fix reserved-mem

From: Caleb Connolly <caleb@...nolly.tech>

[ Upstream commit d77c95bf9a64d8620662151b2b10efd8221f4bcc ]

Fix the upper guard and the "removed_region", this fixes the random
crashes which used to occur in memory intensive loads. I'm not sure WHY
the upper guard being 0x2000 instead of 0x1000 doesn't fix this, but it
HAS to be 0x1000.
