[PATCH 31/41] ARM: ux500: Call appropriate clock initialisation based on DT or !DT booting

[Lee Jones]

The ux500 platform will soon be converted to Device Tree only. When that
happens the old clock initialisation will be ripped out. In the meantime
however, we have to make a decision and call the appropriate
initialisation code manually.
