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 driver model support to the kirkwood SPI driver. Which
is also used on the MVEBU SoC's, now being converted to DM. Non-DM
support is still available for the "older" platforms using this
driver, like kirkwood.

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.

To boot Linux, we should prevent Initramdisk and FDT from going too
high.
Currently, boot_relocate_fdt() checks "fdt_high" environment first,
and then falls back to getenv_bootm_mapsize() + getenv_bootm_low()
if "fdt_high" is missing.
On the other hand, boot_ramdisk_high() only checks "initrd_high" to
get the address limit for the Initramdisk. We also want to let this
case fall back to getenv_bootm_mapsize() + getenv_bootm_low().
