arm64: dts: qcom: qcom6490-idp: Add IPA nodes

This commit adds IPA nodes for the Qualcomm qcm6490 board. It configures
the firmware-name and sets the status to okay, stating that other required
properties are provided by kodiak.dtsi.

[Severity: Medium]
Will the IPA driver fail to probe here due to missing properties?

The commit message states that the qcom,gsi-loader and memory-region
properties are provided by kodiak.dtsi. However, it appears neither
kodiak.dtsi nor this file actually provides them for the ipa node.

Without qcom,gsi-loader, the driver defaults to self-loading and calls
ipa_firmware_load() during initialization.

Because ipa_firmware_load() requires a memory-region property to map the
firmware memory, lacking it will cause the probe to unconditionally abort.

Should these properties be explicitly added to this node to ensure the
device can successfully initialize?
