Move the pci_epc_clear_bar() and pci_epf_free_space() code to respective
helper functions. This allows reusing the helpers in future commits.
This also requires moving the pci_epf_test_unbind() definition below
pci_epf_test_bind() to avoid forward declaration of the above helpers.
No functional change.
