This change allows to keep board description clean and minimalistic.
This is especially helpful if one board may house different CPUs with
different features.
It is applicable to both FPGA-based boards or those that have CPUs
mounted on interchnagable daughter-boards.

Now we may select a particular version of ARC700:
* ARC750D or
* ARC770D
It allows more flexible (or more fine tuned) configuration of U-Boot.
Before that change we relied on minimal configuration but now we may
use specific features of each CPU.
Moreover allows us to escape manual selection of options that
exist in both CPUs but may have say different version like MMUv2 in
ARC750D vs MMUv3 in ARC770D.

With switch to Kconfig we only need very board-specific descriptions in
include/configs.
CPU selection is performed with either defconfig or manually via

Current the MMC support will enable MCI port A, Which is only exist
for 2mmc board.
So by default we need to disable MMC (port A) support. And only enable
it for 2mmc board. Otherwise, dataflash won't work in at91sam9260ek board
as MMC has confliction with Dataflash in the CLK pin.

As the PMECC hardware has different version. In SAMA5D4 chip, the PMECC ip

As the at91cap9adk board is removed by commit: b5508344
(ARM: remove broken "at91cap9adk" board), so the at91cap9
code is not used anymore, and also the document for
