Alexander Shishkin 7b7036d47c intel_th: pci: Use MSI interrupt signalling
Since Intel TH is capable of MSI interrupt signalling, make use of it.
The way it works is, each of the 7 interrupt triggering events has its
own vector in this mode, as opposed to interrupt line delivery, where
all events are signalled via the same line. Failing to enable MSI, the
driver falls back to using an interrupt line.
