MN10300: Provide the functions to fully disable maskable interrupts
The local_irq_disable() function and co. merely raise the interrupt mask on the MN10300 arch to exclude normal interrupts. This still lets other, higher priority maskable interrupts through, such as are used to service gdbstub's serial port and the MN10300 on-chip serial port virtual FIFOs. Provide functions to allow the maskable interrupts to be fully disabled, which will exclude those interrupts.
