This patch set introduces support for MSI(-X) in GICv2m specification,
which is implemented in some variation of GIC400.

This patch set is rebased from: 
    Git tree   : git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git
    Git branch : domain_hierarchy
    Last commit: 97d4ea1f0922fb47dd1b09cd2694b7fa5b519db9

Changes in V9 includes:
  * GICv2m is now adopting the new domain hierarchy, which requires
    GICv2m to implements its own irq_chip and irq_domain, as a child of GIC. 
    GICv2m domain is intialized using the SPI base and the number of SPIs from
    V2M_MSI_TYPER registers (or the override value from DT).

  * Simplified GIC logic that was used to handle MSI stuff. Now the v2m
    stuff is cleanly separated.
