Add clocks to the IPs already described in the pxa device-tree
files. There are more clocks in the clock tree than IPs described in the
current pxa device-tree.
This patch ensures that :
- the current description is correct
- the clocks are actually claimed, so that clock framework doesn't
disable them automatically (unused clocks shutdown)
