5205287554 powerpc/fsl: define binding for fsl mpic interrupt controllers
Define the binding for compatible = "fsl,mpic", including the definition
of 4-cell interrupt specifiers.  The 3rd and 4th cells are needed to
define additional types of interrupt source outside the "normal" external
and internal interrupts in FSL SoCs.  Define error interrupt, IPIs, and
PIC timer sources.

6820fead71 powerpc/fsl_msi: Handle msi-available-ranges better
Now handles multiple ranges, doesn't make assumptions about interrupt
specifier format, and doesn't claim interrupts that don't correspond to an
available range.

Also has some better error checking.

The device tree binding is updated to clarify some existing assumptions.

d524dac927 dt: Move device tree documentation out of powerpc directory
The device tree is used by more than just PowerPC.  Make the documentation
directory available to all.

v2: reorganized files while moving to create arch and driver specific
    directories.
