Add composite video out support.

was tested. It will be enabled on more boards after testing.

2d779b39b4 arm: socfpga: system: Clean up pinmux_config.c
Implement new accessor, sysmgr_get_pinmux_table(), used to obtain pinmux
table and it's size from the QTS-generated pinmux_config.c. The target
here is again to get rid of poluting global namespace by including the
pinmux_config.h into it.

Furthermore, the pinmux_config.h declares some CONFIG_HPS_* macros,
which are explicitly useless to us in U-Boot. Instead, U-Boot does
use DT to detect exactly these configuration options. This patch
makes sure that while this QTS-generated file can stay in the tree,
these obscure macros do not ooze into the namespace anymore.

575d741516 arm: socfpga: scan: Zap iocsr_scan_chain*_table()
Introduce accessor iocsr_get_config_table() for retrieving IOCSR config
tables. This patch is again trimming down the namespace polution.

The IOCSR config tables are used only by scan manager, they are generated
by qts and are board specific. Before this patch, the approach to use
these tables in scan manager was to define an extern variable to silence
the compiler and compile board-specific iocsr_config.c into U-Boot which
defined those extern variables. Furthermore, since these are tables and
the scan manager needs to know the size of those tables, iocsr_config.h
is included build-wide.

This patch wraps all this into a single accessor which takes the scan
chain ID and returns pointer to the table and it's size. All this is
wrapped in wrap_iocsr_config.c board-specific file. The file includes
the iocsr_config.c (!) to access the original tables and transitively
iocsr_config.h . It is thus no longer necessary to include iocsr_config.h
build-wide and the namespace polution is trimmed some more.

93b4abd3a2 arm: socfpga: clock: Clean up pll_config.h
Extract the clock configuration horribleness caused by pll_config.h in
the following manner.

First of all, introduce a few new accessors which return values of
various clocks used in clock_manager.c and use them in clock_manager.c .
These accessors replace those few macros which came from pll_config.h
originally. Also introduce an accessor which returns the struct cm_config
default configuration for the clock manager used in SPL.

The accessors are implemented in a board-specific wrap_pll_config.c
file, whose sole purpose is to include the qts-generated pll_config.h
and provide only the necessary values to the clock manager.

The purpose of this design is to limit the scope of inclusion for the
pll_config.h , which thus far was included build-wide and poluted the
namespace. With this change, the inclusion is limited to just the new
wrap_pll_config.c file, which in turn provides three simple functions
for the clock_manager.c to use.

d1de41d7fa exynos: Add support for spring
Spring is the first ARM-based HP Chromebook 11. It is similar to snow
and it uses the same Samsung Exynos5250 chip. But has some unusual
features. Mainline support for it has lagged snow (both in kernel and
U-Boot). Now that the exynos5 code is common we can support spring just
by adding a device tree and a few lines of configuration.
