x86/PCI: Remove unused HyperTransport interrupt support
There are no in-tree callers of ht_create_irq(), the driver interface for
HyperTransport interrupts, left. Remove the unused entry point and all the
supporting code.
See 8b955b0dddb3 ("[PATCH] Initial generic hypertransport interrupt
support").
