 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.
