* new-exceptions/bspsupport/irq.c: don't disable irqs at the interrupt controller (PIC) during initialization -- this caused problems where some BSPs's BSP_disable_irq_at_pic() routine did not ignore IRQ lines associated with cascaded PICs. Rely on the BSP (BSP_setup_the_pic()) to provide a good initial setup.
