The aspeed_pcie_probe() function calls aspeed_pcie_init_irq_domain()
which allocates pcie->intx_domain and initializes MSI. However, if
platform_get_irq() fails afterwards, the cleanup action was not yet
registered via devm_add_action_or_reset(), causing the IRQ domain
resources to leak.

Fix this by registering the devm cleanup action immediately after
aspeed_pcie_init_irq_domain() succeeds, before calling
platform_get_irq(). This ensures proper cleanup on any subsequent
failure.
