[PATCH v6 2/3] arm64: dts: imx95: Add dma, intr, aer and pme interrupts for PCIe

[hongxing . zhu]

From: Richard Zhu <hongxing.zhu@xxxxxxx>

The current PCIe device tree configuration only defines the MSI
interrupt, which is sufficient for basic PCIe operation but limits
advanced functionality.

Add the following interrupt lines to pcie0 and pcie1 nodes:
- dma: DMA interrupt for PCIe DMA operations
- intr: General controller events and link state changes
- aer: Advanced Error Reporting interrupt
- pme: Power Management Event interrupt

This enables enhanced PCIe features and capabilities that were
previously unavailable due to missing interrupt definitions.
