This enhancement allows to mask all available common interrupts
in IDU interrupt controller in boot time since the kernel can
discover a number of them from the build register. Also now there
is no need to specify in device tree a list of used core interrupts
by IDU. E.g. before:
idu_intc: idu
After reset all interrupts in the core interrupt controller has
the highest priority P0. If the platform supports Fast IRQs and
has more than 1 banks of registers then CPU automatically switch
banks of registers when P0 interrupt comes.
The problem is that the kernel expects that by default switch

This structure is necessary for retrieving of supported
number of common interrupts in IDU interrupt controller.

A summary:
* Use build registers for getting numbers of interrupts both for
core interrupt controller and for IDU interrupt controller.
* Set a default priority for all core interrupt to prevent
unexpected switching of banks of registers.
* Remove option for setting number of interru
When you set a value of ARC_NUMBER_OF_INTERRUPTS option
it affects only a size of the interrupts table but macros
for number of virtual interrupts (NR_IRQS) and for number
of hardware interrupts (NR_CPU_IRQS) remain unchanged.
Moreover usage of ARC_NUMBER_OF_INTERRUPTS is bad for
portability since
Also add new macro ARC_REG_STATUS32 for the address of STATUS32
auxiliary register. It is better to use it instead of magic numbers.
