David Daney 87161ccdc6 MIPS: Octeon: Fix broken interrupt controller code. 
Since 3.6.0-rc1,  We are getting many messages like:

WARNING: at kernel/irq/irqdomain.c:444 irq_domain_associate_many+0x23c/0x260()
Modules linked in:

.

Both the CIU and GPIO interrupt domains were somewhat screwed up.

For the CIU domain, we need to call irq_domain_associate() for each of
the preassigned irq numbers.  For the GPIO domain, we were applying
the register bit offset in octeon_irq_gpio_xlat, but it should be done
in octeon_irq_gpio_map instead.

Also: Reserve all 8 'core' irqs for the 'core' irq_chip so that they
don't get used by the other domains.  Remove unused OCTEON_IRQ_*
symbols.
