This patchset adds/fixes the following functionality specific to the
1. Fix support for timer group B interrupts. Previously these were
not getting initialized.

2. Use the MPIC_LARGE_VECTORS flag while intializing FSL MPIC.
This prevents us from eating in to hardware vector number
space (MSIs) while setting up internal sources.

3.Cascaded handling for the MPIC error interrupt. This is possible
with FSL MPIC version >= 4.1.

The patches are based on "next" branch of Benjamin Herrenschmidt's powerpc
linux tree.

Varun Sethi (3):
  Support time group b on freescale chips.
  Use MPIC_LARGE_VECTORS flag for Freescale MPIC.
  Add support for cascaded error interrupt handling.
