This adds support for the U9540 variant of the U8500 series. This is an application processor without internal modem. This is the most basic part with ASIC ID, CPU-related fixes, IRQ list, register ranges, timer, UART, and L2 cache setup. This is based on a patch by Michel Jaouen which was rewritten to fit with the latest 3.3 kernel. ChangeLog v1->v2: deleted the irqs-db9540.h file since we expect to migrate to using Device Tree for getting the IRQs to devices. ChangeLog v2->v3: introduced a fixed virtual offset for the ROM as suggested by Arnd Bergmann.
