Subject: [PATCH v3 2/4] ASoC: intel: avs: Use pure devres PCI

pci_request_regions() is a hybrid function which becomes managed if
pcim_enable_device() was called before. This hybrid nature is deprecated
and should not be used anymore.

Replace pci_request_regions() with the always-managed function
pcim_request_all_regions().

Remove the goto jump to pci_release_regions(), since pcim_ functions
clean up automatically.
