[SeaBIOS] [PATCHv4 3/3] acpi: remove _RMV

The macro gen_pci_device is used to add _RMV
method to a slot device so it is no longer needed:
presence of _EJ0 now indicates that the slot is ejectable.
It is also placing two devices with the same _ADR
on the same bus, which isn't defined by the ACPI spec.
So let's remove it.
