In the process of converting sector-based interfaces to bytes,
I'm finding it easier to represent a byte count as a 64-bit
integer at the block layer (even if we are internally capped
by SIZE_MAX or even INT_MAX for individual transactions, it's
still nicer to not have to worry about truncation/ove

That is why I think we can consider a possibility of forgetting about ACPI
hot plug in pcie-pci bridge and use only SHPC (with some correcting work).
Especially since q35 is used only for 'modern' Windows guests and there're
no big problems with SHPC on Linux guests.

link's check callback is supposed to verify/permit setting it,
however currently nothing restricts it from misusing it
and modifying target object from within.
Make sure that readonly semantics are checked by compiler
