arm: move irq_vector_table to common location

Browse source 
We don't support hard-coding vectors in this table anymore.
If someone really wants to do this, they can set
IRQ_VECTOR_TABLE_CUSTOM and define their own.

/**
* @file
* @brief IRQ part of vector table
*
* 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 platform is written so that device ISRs are installed directly in
* the vector table, they are enumerated here.
