[PULL] msi-map support and msi-parent updates for 4.4

[Marc Zyngier]

Hi Thomas,

Here's a number of patches that introduce the msi-map DT property, and
puts it to a good use is the MSI layer. The msi-parent property also
gets reworked in order to cope with its sideband information
extension.

Please pull!

Thanks,

	M.
