[PATCH v2 1/2] arm64: dts: qcom: sm8450: Remove unneeded reserved memory nodes

[Esteban Urrutia via B4 Relay]

From: Esteban Urrutia <esteuwu@proton.me>

These nodes are not present on downstream device trees and only take memory
away from the AP.
No crashes occur without these nodes, so remove them.

[PATCH v2 2/2] arm64: dts: qcom: sm8450: Add mode-switch property to qmpphy

[Esteban Urrutia via B4 Relay]

From: Esteban Urrutia <esteuwu@proton.me>

USB QMP PHY is a possible handler of altmode switching, so add this
property.
