mb/asrock/h110m: Add PEG Gen3 support

This patch adds support PCIe Gen 3 with 8GT/s link speed for PEG x16
slot. All parameters for FSP are set during initialization in
romstage. Now there is no need to additionally configure the FSP
before building the ROM image.

Tested on Intel Core i5-6600 processor with the following devices:
  - LP11000e Fibre Channel HBA (Gen2 x8);
  - PEX8734 PCIe Fabric/Switch (Gen3 x16);
  - NVIDIA GeForce GTX 1060 GPU (Gen3 x16).

GPU works with an nouveau and proprietary driver under Ubuntu 18.04.2
(4.15.0-46-generic GNU/Linux kernel). Discrete graphic card is used
as primary device for display output. Dynamic switching is not yet
supported.

Tianocore (edk2-stable201811-216-g51be9d0) is used as the payload.
