It can also be used to describe non-PMT capabilities. Like PMT, these capabilities are also enumerated using PCIe Vendor Specific registers in config space. In order to better support these devices without the confusion of a dependency on MFD_INTEL_PMT, remove the OOBMSM device from intel_pmt so that it can be later placed in its own driver. Since much of the same code will be used by intel_pmt and the new driver, create a new file with symbols to be used by both. While performing this split we need to also handle the creation of platform devices for the non-PMT capabilities. Currently PMT devices are named by their capability (e.g. pmt_telemetry). Instead, generically name them by their capability ID (e.g. intel_extnd_cap_2). This allows the IDs to be created automatically. However, to ensure that unsupported devices aren't created, use an allow list to specify supported capabilities. Signed-off-by: David E.
