x86/pci: Clean up open-coded PCIBIOS return code mangling
Per PCI Firmware spec r3.3, sec 2.5.2, 2.6.2, and 2.7, the return code for
these PCI BIOS interfaces is in 8 bits of the EAX register. Previously it
was extracted by open-coded masks and shifting.
Name the return code bits with a #define and add pcibios_get_return_code()
to extract the return code to improve code readability. In addition,
replace zero test with PCIBIOS_SUCCESSFUL.
No functional changes intended.
