[ARM] 5473/1: U300 core machine support

This adds core support for the ST-Ericsson U300 series
platforms: U300, U330, U335 and U365. Supports memory
mappings, interrupt controller, system timer (clocksource
and clockevents), and binds to the existing drivers for
the PrimeCells used in this design: PL190 (VIC), PL180
(MMC/SD host) and PL011 (UART). This is intented to serve
as starting point for our mainling work, more patches to
follow.
