arm64: dts: qcom: use qcom,gsi-loader for IPA

Depending on the platform, either the modem or the AP must load GSI
firmware for IPA before it can be used.  To date, this has been
indicated by the presence or absence of a "modem-init" property.

That mechanism has been deprecated.  Instead, we indicate how GSI
firmware should be loaded by the value of the "qcom,gsi-loader"
property.

Update all arm64 platforms that use IPA to use the "qcom,gsi-loader"
property to specify how the GSI firmware is loaded.

Update the affected nodes so the status property is last.
