am335x irq handling improvement
This patch makes the following changes to the Beaglebone IRQ handling code:
- Disable support for nested interrupts.
- Detect spurious IRQs using the SPURIOUSIRQ field of the INTC_SIR_IRQ register.
- Acknowledge spurious IRQs by setting the NewIRQAgr bit of the INTC_CONTROL
register. This cleans the SPURIOUSIRQ field and allows new interrupts
to be generated.
- Improve the get_mir_reg function a bit.
Closes #2580.
