[PATCH 0/4] Migrate PXA27x platforms to clock framework

As the RFC posted in [1] didn't meet an unrivaled success for
review, I'm posting this serie for PXA27x transition to clock
framework.

This transition is needed :
 - to enable device-tree drivers port, as clocks are needed almost
   everywhere
 - to enable the long term multi-platform kernel to support PXA

As I had said before, this serie aims at :
 - keeping legacy platforms working (ie. without device-tree)
 - enable PXA27x to work with a device-tree kernel, and hence
   open the way to drivers conversion
 - be robust enough to support pxa25x and pxa3xx later inclusion
   with almost no change to clk-pxa-dt.c.

As this serie is holding the rest of the device-tree drivers
port, I'd like it to be reviewed, even it's an old unsexy
platform.

Cheers.
