Subject: [PATCH AUTOSEL 5.12 088/102] arm64: dts: qcom: sm8150: Disable Adreno and modem by default

From: Konrad Dybcio <konrad.dybcio@...ainline.org>

[ Upstream commit b1dc3c6b3dabbedaf896a3c1a998da191c311c70 ]

Components that rely on proprietary (not to mention signed!) firmware should
not be enabled by default, as lack of the aforementioned firmware could cause
various issues, from random errors to straight-up failing to boot.

Not enabling modem back on the HDK, as it uses a sa8150.

Also fixed a sorting mistake in both boards' dt while at it.
