x86/of: Return consistent error type from x86_of_pci_irq_enable()
x86_of_pci_irq_enable() returns PCIBIOS_* code received from
pci_read_config_byte() directly and also -EINVAL which are not
compatible error types. x86_of_pci_irq_enable() is used as
(*pcibios_enable_irq) function which should not return PCIBIOS_* codes.
Convert the PCIBIOS_* return code from pci_read_config_byte() into
normal errno using pcibios_err_to_errno().
Fixes: 96e0a0797eba ("x86: dtb: Add support for PCI devices backed by dtb nodes")
