Subject: [PATCH AUTOSEL 6.1 09/35] arm64: dts: msm8994-angler: fix the memory map

From: Dominik Kobinski <dominikkobinski314@...il.com>

[ Upstream commit 380cd3a34b7f9825a60ccb045611af9cb4533b70 ]

Add reserved regions for memory hole and tz app mem to prevent
rebooting. Also enable cont_splash_mem, it is the same as the
generic 8994 one.
