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.

Make it a sub-menu of "General setup" like Linux Kernel.

For similar reasons to why the Linux Kernel has an EXPERT option, we too
want an option to allow for tweaking of some options that while normally
should remain hidden, may need to be changed in some cases.

Defining CONFIG_SYS_TEXT_BASE in config.mk is very old style.

Create CONFIG_SYS_TEXT_BASE option in Kconfig, but let it
depend on CONFIG_SPARC because we do not want to disturb
the other architectures that still define CONFIG_SYS_TEXT_BASE
in their header files.

CONFIG_TPL should not be enabled for boards that do not have TPL.
CONFIG_SUPPORT_TPL introduced by this commit should be "select"ed
by boards with TPL support and CONFIG_TPL should depend on it.

This commit moves:
  CONFIG_OF_CONTROL
  CONFIG_OF_SEPARATE
  CONFIG_OF_EMBED
  CONFIG_OF_HOSTFILE

Because these options are currently not supported for SPL,
the "Device Tree Control" menu does not appear in the SPL
configuration.

Note:
zynq-common.h should be adjusted so as not to change the
default value of CONFIG_SPL_FAT_LOAD_PAYLOAD_NAME.

CONFIG_DEFCONFIG_LIST specifies the default defconfig.
It is used by "make savedefconfig" when .config is missing.
But that's it.  I could not find other useful cases.

As a side effect, CONFIG_DEFCONFIG_LIST="configs/sandbox_defconfig"
is contained in .config of every target board, which some people
think is odd.  So, let's remove it.
