ARM: vexpress: Remove non-DT code
Now, with the CLCD DT support available, there is no more reason to keep the non-DT support for V2P-CA9. Removed, together with "some" supporting code. It was necessary to make PLAT_VERSATILE_SCHED_CLOCK optional and selected by the machines still interested in it.
