This change updates the ux500 specific outer cache code to use
the new *_relaxed() I/O accessors.

The generic version of l2x0_inv_all is only called just after disabling
the L2 cache and is surrounded by a spinlock. However, we're not really
turning off the L2 cache right now, and the PL310 does not support
exclusive accesses (used to implement the spinlock). So, the
invalidation needs to be done without the spinlock.

This adjusts the clockrate for the MTU timer. On the different
UX500 variants this rate is different. The platform can also have
been set up at hardware initialization, bootloader or early init
for different clock speeds. To have the clock framework available
early so the timers can use them, the clock initialization for
Nomadik and ux500 is moved to IRQ init time. A custom per-clock
callback is added to handle special cases like this.
This solves a user-visible bug: without this patch the current
UX500 platforms will not be synchronized to wall-clock time and
the platform will drift in time.

Introduce devices.c, for placing devices common among Ux500 SoCs. Start
with the PL031 device.

Move IRQ initialization and common io mapping setup code to cpu.c,
renaming U8500* to UX500* along the way.
