These source files contain only level-2 cache initialization code,
so rename them to make that fact more obvious.

Add a new config option ARCH_BCM_MOBILE_L2_CACHE that allows support
for level-2 cache to be enabled or disabled at build time for
BCM218XX and BCM21664 family SoCs.

Build support for SMC only if it's required (currently it's only
required for to support level 2 cache control).

If arch/arm/mach-bcm/kona.c gets compiled, ARCH_BCM_MOBILE_L2_CACHE
must have been selected, which implies CONFIG_CACHE_L2X0 is set.
There is therefore no need to check CONFIG_CACHE_L2X0 at the top
of kona_l2_cache_init(), so get rid of that check.

In preparation for future SoCs, move kona_l2_cache_init() from board
specific board_bcm281xx.c to shared kona.c, so multiple SoC families
can make use of it. Also change the return type to "void", since we
never look at the return code anyway.

This device extends the uio_pdrv_genirq driver to provide limited
dynamic memory allocation for UIO devices.  This allows UIO devices
to use CMA and IOMMU allocated memory regions. This driver is based
on the uio_pdrv_genirq driver and provides the same generic interrupt
handling capabilities.  Like uio_prdv_genirq,
a fixed number of memory regions, defined in the platform device's
.resources field are exported to userpace. This driver adds the ability
to export additional regions whose number and size are known at boot time,
but whose memory is not allocated until the uio device file is opened for
the first time.  When the device file is closed, the allocated memory block
is freed.  Physical (DMA) addresses for the dynamic regions are provided to
the userspace via /sys/class/uio/uioX/maps/mapY/addr in the same way as
static addresses are when the uio device file is open, when no processes
are holding the device file open, the address returned to userspace is
DMA_ERROR_CODE.

This patch implements PRUSS (Programmable Real-time Unit Sub System)
UIO driver which exports SOC resources associated with PRUSS like
I/O, memories and IRQs to user space. PRUSS is dual 32-bit RISC
processors which is efficient in performing embedded tasks that
require manipulation of packed memory mapped data structures and
handling system events that have tight real time constraints. This
driver is currently supported on Texas Instruments DA850, AM18xx and
OMAP-L138 devices.
For example, PRUSS runs firmware for real-time critical industrial
communication data link layer and communicates with application stack
running in user space via shared memory and IRQs.

Using a device_initcall() for initializing the voltage regulator
on DA850 is not such a good idea because it gets called for all
platforms - even those who do not have a regulator implemented.
This leads to a big fat warning message during boot-up when
regulator cannot be found.

Instead, tie initialization of voltage regulator to cpufreq init.
Define a platform specific init call which in case of DA850 gets
used for initializing the regulator. On other future platforms it
can be used for other purposes.

Add ADV7343 I2C based video encoder driver. This follows the
v4l2-subdev framework. This driver has been tested on TI DM646x EVM. It
has been tested for Composite and Component outputs.

Updates as per review by Mauro Chehab, added support for more standards
supported by the encoder. Also adding the missed out signed-offs.Tested
only NTSC and PAL standards.
