void AddCapabilityInternal (uint8_t capability_id, uint8_t position, uint8_t size)

Capabilities are the hardest part to implement because if a device expects a capability

at a given address in configuration space then it's possible they will want to write to it.

Additionally, vendor capabilities are of a variable size which is read from the capability

at runtime. To further complicate things, particular devices will have registers in their

configuration space that the device may be expected to use but which are not exposed

through any PCI base address register mechanism. This makes it risky to lay out a

capability wherever we wish for fear it may overlap with one of these spaces. For this

reason we do no validation of the capability's setup in configuration space besides writing

the capability id and next pointer. The test author is responsible for setting up the

layout of the capabilities as necessary to match their device, but we can provide helper

methods to ensure they're doing it properly.
