Subject: [PATCH v1 1/6] arm64: dts: qcom: move pcie6a type change from X1P42100 to X1P42100-crd

It appears at least on some devices (Asus Zenbook A14, x1-26-100) change
of pcie6a_phy's compatible breaks the controller. Move compatible change
from generic x1p42100.dtsi to CRD's specific x1p42100-crd.dts instead.
