 Intel Non-transparent Bridge needs special BIOS setting. Since the PMD only
 supports Intel Skylake platform, introduce BIOS setting here. The referencce

+- Enable NTB bars and set bar size of bar 23 and bar 45 as 12-29 (4K-512M)

 - Disable split bars for both hosts.
 - Set crosslink control override as DSD/USP on one host, USD/DSP on
   another host.
