While the Exynos5420 chip is used in both Smdk5420 and in the Peach-Pit
line of devices, there could be other boards using the same chip, so a
common configuration file is being added (exynos5420.h) as well
as two common device tree files (exynos54xx.dtsi & exynos5420.dtsi).

The peach board as declared in boards.cfg is a copy of smdk5420
declaration. The configuration files are similar, but define different
default device trees, console serial ports and prompts.

The device tree files for smdk5420 and peach-pit inherit from the same
common file.

This patch enables to run Origen board on device tree.

Uart, DRAM and MMC init functions are removed as their
generic replacements form the common board file are used.

The config file is modified to contain only board specific options.

Commit 5ab502cb gathered all device tree sources
to arch/$(ARCH)/dts/.
So tegra124-venice2.dts also must go to arch/arm/dts directory
to build venice2 board.

(Commit 5ab502cb had been posted before venice2 board support
was merged. So an unvisible conflict happened.)

It is convenient to have all device trees on the same SoC compiled.
It allows for later easy repackaging without the need to re-run
the make file.

  - Build device trees with the same SoC under arch/$(ARCH)/dts

  - Copy the one specified by CONFIG_DEFAULT_DEVICE_TREE or
    DEVICE_TREE=... to dts/dt.dtb
