Counting the U9540 and the new U8540 as a U8500 family member
does not work. Instead, split the function in two:
cpu_is_u8500_family() covering U8500 and U8520
cpu_is_ux540_family() covering U9540 and U8540
This works much better in practice. Update users to keep the
same behaviour.

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.

This adds a few CPU identification functions for the U5500 variants.
Contains portions of code written by Rabin Vincent.

This makes the core detect the DB8500 V2.0 and V2.1 ASICs, and
add a convenience macro for "V2 or later".
