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
menuconfig.

It makes sense to specify CONFIG_SYS_CLK_FREQ in "configs/xx_defconfig"
instead of "include/configs/xxx.h" because then header will be reusable
across boards with different CPU clocks.
Also this nice to have an ability for end user to tune this value
himself via "menuconfig".
For now I'm only applying this change to all ARC configs because
otherwise scope of change will be huge.

Arcangel4 is a FPGA-based development board that is used for prototyping and
verificationof of both ARC hardware (CPUs) and software running upon CPU.
This board avaialble in 2 flavours:
* Little-endian (arcangel4)
* Big-endian (arcangel4-be)
