[PATCH v2 2/6] arm64: dts: qcom: qcm6490-shift-otter: Remove thermal zone polling delays

[Luca Weiss]

From: Alexander Martinz <amartinz@shiftphones.com>

As with all other devices in commit 7747a49db7e5 ("arm64: dts: qcom:
sc7280-*: Remove thermal zone polling delays"), apply the same change to
this device as the delays are assumed to be equal to "0" if not set.

[PATCH v2 3/6] arm64: dts: qcom: qcm6490-shift-otter: Add missing reserved-memory

[Luca Weiss]

From: Alexander Martinz <amartinz@shiftphones.com>

It seems we also need to reserve a region of 81 MiB called "removed_mem"
otherwise we can easily hit memory errors with higher RAM usage.

If you make sure CONFIG_MEMTEST is enabled, you can boot with memtest=1
on the command line to catch such issues, without relying on "higher RAM
usage" (or randomness).
