Patch series For U6/U6715 platform support

[Philippe Langlais]

Hi,

This patch series is almost the final one, if no more comment.
I only change the changelog of [PATCH 5/5] to my previous submission.
The 3 first patches are U6715 ARM platform concern only, may be merged
in Russell arm tree.
The 2 latest patches concern the 8250 serial driver, Greg must update
the changelog of patch "U6715 16550A serial driver support" in linux-next
tree and merge the platform U6715 serial driver patch synchronized with
Russell ack (see Andrew previous suggestion). 

Thanks
Philippe
