ARM: msm: Fix gic irqdomain support 

As of

    commit 75294957be
    Author: Grant Likely <grant.likely@secretlab.ca>
    Date:   Tue Feb 14 14:06:57 2012 -0700

        irq_domain: Remove 'new' irq_domain in favour of the ppc one

the ARM gic controller uses proper irq domains.  Fix the MSM gic
initialization and DT so that it works again.
