xlnx-zynqmp: Connect the AHCI SATA device

The AHCIState strucut can either have AHCIPCIState or SysbusAHCIState

as a parent. The ahci_irq_lower() and ahci_irq_raise() functions assume that it is always AHCIPCIState, which is not always the case, which causes a seg fault. Verify what the container of AHCIState is before setting the PCIDevice struct.

The problem with the standard ones is that they contain asserts. So you can't do a test to see if the cast is possible, which is what I want to do.

The problem with the standard ones is that they contain asserts. So you can't do a test to see if the cast is possible, which is what I want to do.

But the original code uses object_dynamic_cast which should be a non-asserting cast attempt. What was the assertion you were getting?

Oh! I see what you mean. I can use the object_dynamic_cast() instead. I thought you meant to use the macros that are defined.

If there are no other comments I will re-send the series.
