OK Mike, I'll fix this. This is probably because pxa27x_clocks array is not
__init, and it references parents which are __init. I was lazy letting
pxa27x_clocks not __init because I reuse the internal fields "hw" and "gate->hw"
later (hence I didn't leave the __init).
This is a bit dirty and I'll launder it.

Moreover, I have one fix which I had fixed wrt boot ordering : the
postcore_init() must die. The reason behind is that I have no guarantee of
ordering between clocks init and clocksource init, and clocksource relies on
clocks.

The right way will be AFAIK to call the core clocks init :
 - within the device-tree initialization function : pxa27x_dt_clocks_init()
 calls pxa27x_clocks_init9)
 - directly from pxa27x_init() or pxa_timer_init() in non-device tree setup

I would feel more comfortable if :
 - you take the 4 first ones (3 clock ones + 1 arm pxa header bit definitions)
 - Haojian takes the last 2 ones (pxa ones)

I will check that taking only the first 4 ones doesn't break anything, in case
there is a merge window hipcup.

Cheers.
