ASoC: amd: acp: Use pcim_iomap_region() in acp-pci

Browse source

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.
