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.

Here we make use of the new System-On-Chip bus driver to export
vital SoC information out to userspace via sysfs. This patch
provides a data structure of strings to populate the base
nodes found in:
/sys/devices/soc[0|1|2|...]/[family|machine|revision|soc_id].
It also adds one more node as requested by ST-Ericsson.
'process' depicts the way in which the silicon was manufactured.

The DB8500 ED (Early Drop) and V1 are only available inside of
ST-Ericsson or partners, we have actively replaced and scrapped
these prototypes. All Nova products on the open market (such as
the Snowball board) are based on V2 and later ASIC variants.
So let us focus on supporting the silicon that will be used and
delete this to get a clear overview.

This patch adds support for db8500 chip version 2.
The TCDM memory address of the PRCMU is changed and
dynamic detection of that is added.

This patch adds support for checking if the digital baseband (DB)
System-on-Chip (aka "cpu) ASIC hardware version is 1.0, 1.1 or
2.0. We print the result in the bootlog, the functions are then
used for runtime decisions based on hardware version.

This makes sure the DMA40 driver will also work on the oldest
silicon revisions that have the on-chip memory on another location
in the DB8500 and also requires explicit suspend before starting
or resuming a logical channel.

This follows on the patch to allocate LCLA dynamically: the
on-chip memory is needed for other things so now that that
we're using it dynamically we can remove the LCLA resource
altogether and free up some ESRAM memory.

Split up all the hardware register definitions previously found in
hardware.h into per-SoC files db8500-regs.h and db5500-regs.h. Rename a
couple of macros to prepare for sharing code between the variants.
