The frequency for the Kona timer can either be specified through the
device tree or determined by checking the rate of the clock specified
in the device tree. Update the documentation to reflect both ways.

This patchset renames all uses of "bcm," name bindings to
"brcm," as they were done prior to knowing that brcm had
already been standardized as Broadcom vendor prefix
(in Documentation/devicetree/bindings/vendor-prefixes.txt).
This will not cause any churn on devices because none of
these bindings have made it into production yet.
Also rename the the following dt binding docs that had "bcm,"
in their name for consistency:
- bcm,kona-sdhci.txt -> kona-sdhci.txt
- bcm,kona-timer.txt -> kona-timer.txt

This adds support for the Broadcom timer, used in the following SoCs:
BCM11130, BCM11140, BCM11351, BCM28145, BCM28155
Updates from V6:
- Split DT portion into a separate patch
Updates from V5:
- Rebase to latest arm-soc/for-next
Updates from V4:
- Switch code to use CLOCKSOURCE_OF_DECLARE
Updates from V3:
- Migrate to 3.9 timer framework updates
Updates from V2:
- prepend static fns + fields with kona_
Updates from V1:
- Rename bcm_timer.c to bcm_kona_timer.c
- Pull .h into bcm_kona_timer.c
- Make timers static
- Clean up comment block
- Switched to using clockevents_config_and_register
- Added an error to the get_timer loop if it repeats too much
- Added to Documentation/devicetree/bindings/arm/bcm/bcm,kona-timer.txt
- Added missing readl to timer_disable_and_clear
Note: bcm,kona-timer was kept as the 'compatible' field to make it
specific enough for when there are multiple bcm timers (bcm,timer is
too generic).

In order to start upstreaming Broadcom SoC support, create
a starting hierarchy, arch and dts files.
The first support SoC family that is planned is the
BCM281XX (BCM11130/11140/11351/28145/28155) family of dual A9 mobile
SoC cores.
This code is just the skeleton code for get the machine upstreamed. It
has been made MULTIPLATFORM compatible.
Next steps
----------
Upstream a basic set of drivers - sufficient for a console boot to
ramdisk. These will includer timer, gpio, i2c drivers.
After this basic set, we will proceed with a more comprehensive set
of drivers for the 281XX SoC family.
v2 patch mods
--------
- Remove l2x0_of_init call as there were problems with the code.
A separate patch will be submitted with cache init code
- Rename capri files and refs to bcm281xx-based names
- Add bcm281xx binding doc
- various misc cleanups
v3 patch mods
-------------
- Remove extra #include lines
- Remove remaining references to capri
- dt uart chipset string added
- cleaned up chip # references
v4 patch mods
-------------
- swap order of compatible definitions for uart
- fix typo
v5 patch mods
-------------
- Rename bcm281xx to bcm11351 in dts+code,
leaving references to bcm281xx only in help+comments.
v6 patch mods
-------------
- fix typo in uart 'compatible' string
