The function Arch_finaliseInterrupt() is empty now and can be removed as
it serves no purpose any longer. There has never been a guarantee that
it gets only called due to kernel entry caused by an interrupt. Instead,
getActiveIRQ() is called in various places of the kernel to check if
there is a pending interrupt. There is a guarantee that the generic
kernel code calls ackInterrupt() within the same kernel entry call
path eventually, when it has finished processing this interrupt. Any
architecture or platform specific cleanup can be done there is this is
necessary.
