nvidia/ck804: make Message Signaled Interrupts work

Hardware / Coreboot - Jonathan A. Kollasch [kollasch.net] - 2 February 2015 17:47 UTC

Use HT MSI Mapping capability register at 0xe0 in CK804 HT device to enable HT MSI Mapping so that MSIs work. Prior to this change PCIe devices downstream of the CK804 with MSI enabled would fail to actually assert their interrupt. Tested on msi/ms7135 and winent/mb6047 running Debian GNU/Linux 7.0 (wheezy).
