add minimal code to tartc_irq(), our trampoline from low-level IRQ isr: upon entering (when core IRQ is asserted) we read irq status from tairqc and execute interrupt handler for every intrno in tairqc status register. be sure to mask all (really all) unwanted interrupts on attachment; explicitly unmask intr no. 4 (Real Time Clock) so we can see if it all is working or not :) this completes irq-related chain: RTC -intr-> IRQC -irq-> CPU Core enters IRQ_mode and jumps to 0x00000018 (_vector_irq): _vector_irq -> irq_trampoline -> irq_trampoline_func (which is tairqc_irq) -> tairqc_irq (read irqc status) -> (execute interrupt handlers for every source) -> tartc_interrupt()

add tairqc, driver for testarm Interrupt Controller Unit; this irqc contains only three registers: intr status, mask and unmask. on testarm we will be invoked from low-level when CPU Ext. IRQ is asserted. devconfig machinery will support vectors-table allowing us to switch control flow based on this table into devices' interrupt handlers he-he, still more work on the road, but i need to commit it to work on it.
