in the error count. From Leo (2014-4-17).
* arch/arm/src/sam34/sam_irq.c: Fix initialization of the default
priorities (2014-4-17).
* arch/arm/src/kinetis/kinetis_irq.c, lpc17xx/lpc17_irq.c, and
tiva/tiva_irq.c: Modify the logic to disables the interrupts and sets
the default interrupt priority so that it uses the ICTR to get the
number of interrupt lines/registers. This is instead of using some
fixed number of initializations based a priori knowledge of the number
of interrupt lines in the MCU. This logic is untested on some MCUs
on initial check-in0 (2014-4-17).
