Add the "spi-flash" compatible string so that the generic sf_probe
driver can probe the SPI flash on the theadorable Armada-XP board.

This patch adds support for Altera StratixV bitstream programming. 2 FPGAs
are connected to the SPI busses. This patch uses board specific write
code to program the bitstream via SPI direct write mode.

This patch adds support for the Armada XP (MV78260) based theadorable
board. Its equipped with onboard DDR3, UART, ethernet, I2C, SPI NOR,
LCD and SATA (SSD) interfaces / devices.

Two defconfigs are added:

theadorable_defconfig:
The production U-Boot version with a stripped down drivers and feature
list. This removes networking, USB and PCI support.

theadorable_debug_defconfig:
The debugging / testing U-Boot version with full support for all drivers.

This is needed for the upcoming ethernet DM conversion of the maxbcm
board. The configuration of the PHY is then extracted from the DT
instead of using the defines from the config header.

This patch enables the DM support for the SPI driver and the
SPI NOR flash chips. Some MVEBU boards boot from SPI NOR, so
adding the aliases and enabling CONFIG_DM_SEQ_ALIAS is needed
here.

This patch adds full DM support to the SPL on MVEBU. Currently
only serial is supported. Other drivers will follow.

This patch also adds the necessary config values for the DEBUG UART
to the MVEBU defconfig files. This came in handy while implementing
this DM support.

Additionally, the mvebu specific SPL linker script is removed and
this common one is used instead:

   arch/arm/cpu/u-boot-spl.lds

This common linker script already handles all special cases. No need
to reinvent the wheel for MVEBU here.

These will be needed by the upcoming DM (driver model) support for
the Armada XP / 38x SoC's. This will provide DT based probing.

The dts files are copied 1:1 from the Linux kernel release v4.2.
