Add support for generic BCM SoC chipsets
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
