Convert acp-pci to the pcim-managed PCI life-cycle. Replace pci_enable_device() with pcim_enable_device() and fold the open-coded pci_request_regions() + devm_ioremap() pair into a single pcim_iomap_region() call for BAR0, which reserves and iomaps the register window. This lets the driver drop the manual pci_release_regions() and pci_disable_device() calls from the probe error path; pcim releases the device and region automatically on detach or probe failure. The error check moves from a NULL test to IS_ERR(), since pcim_iomap_region() returns an IOMEM_ERR_PTR on failure. The child platform devices only use devm_ioremap() on their sub-range of BAR0 (no request_mem_region), so reserving the full BAR0 here does not conflict with them.
