[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.
