Tigerlake EDS(#575681) section 3.4.3 describes host bridge REGBAR(MCHBAR) + 7110h for IOM REGBAR with size 1600h. IOM has a port ID 0xc1. MCHBAR is programmed with 0xfedc0000. IOM REGBAR is determined from mmio (MCHBAR + 0x7110), which has value 0xfb000000. IOM has base address 0xfbc10000 from IOM REGBAR + (0xc1 << 16). BUG=:b:156016218 TEST=Built and booted on Volteer.
