Use ARM Global Timer as clocksource instead of the PIT timer. This
leaves the PIT timer for other users e.g. the secondary Cortex-M4
core. Also, the Global Timer has double the precission (running at
pheripheral clock compared to IPG clock) and a 64-bit incrementing
counter register.

Theoretically we could remove the PIT driver now. But we could also
enable both drivers, but is having two clock source useful for the
Kernel at all?
