DESCRIPTION
This file contains the IRQ part of the vector table. It is meant to be used
for one of two cases:

a) When software-managed ISRs (SW_ISR_TABLE) is enabled, and in that case it
   binds _isr_wrapper() to all the IRQ entries in the vector table.

b) When the BSP is written so that device ISRs are installed directly in the
   vector table, they are enumerated here.
