x86/ioapic: Remove unused IO_APIC_irq_trigger() function

Browse Source 
The function isn't used since commit:

  5ad274d41c ("x86/irq: Remove unused old IOAPIC irqdomain interfaces")

Removing it fixes the following warning when building with clang:

  arch/x86/kernel/apic/io_apic.c:1219:19: error: unused function
      'IO_APIC_irq_trigger' [-Werror,-Wunused-function]
