Subject: [PATCH AUTOSEL 6.2 02/25] ARM: dts: qcom: apq8026-lg-lenok: add missing reserved memory

From: Luca Weiss <luca@...tu.xyz>

[ Upstream commit ecd240875e877d78fd03efbc62292f550872df3f ]

Turns out these two memory regions also need to be avoided, otherwise
weird things will happen when Linux tries to use this memory.
