kconfig: add CONFIG_SYS_{ARCH, CPU, ...} type def to arch/Kconfig

This commit adds the type definitions (+ help messages) of
CONFIG_SYS_{ARCH, CPU, SOC, VENDOR, BOARD, CONFIG_NAME} to arch/Kconfig,
which would save lots of type defs for taget boards.
(See also the next commit.)

+config SYS_ARCH
+       string
+       help
+         This option should contain the architecture name to build the
+         appropriate arch/<CONFIG_SYS_ARCH> directory.
+         All the architectures should specify this option correctly.
+
+config SYS_CPU
+       string
+       help
+         This option should contain the CPU name to build the correct
+         arch/<CONFIG_SYS_ARCH>/cpu/<CONFIG_SYS_CPU> directory.
+
+         This is optional.  For those targets without the CPU directory,
+         leave this option empty.
+
+config SYS_SOC
+       string
+       help
+         This option should contain the SoC name to build the directory
+         arch/<CONFIG_SYS_ARCH>/cpu/<CONFIG_SYS_CPU>/<CONFIG_SYS_SOC>.
+
+         This is optional.  For those targets without the SoC directory,
+         leave this option empty.
+
+config SYS_VENDOR
+       string
+       help
+         This option should contain the vendor name of the target board.
+         If it is set and
+         board/<CONFIG_SYS_VENDOR>/common/Makefile exists, the vendor common
+         directory is compiled.
+         If CONFIG_SYS_BOARD is also set, the sources under
+         board/<CONFIG_SYS_VENDOR>/<CONFIG_SYS_BOARD> directory are compiled.
+
+         This is optional.  For those targets without the vendor directory,
+         leave this option empty.
+
+config SYS_BOARD
+       string
+       help
+         This option should contain the name of the target board.
+         If it is set, either board/<CONFIG_SYS_VENDOR>/<CONFIG_SYS_BOARD>
+         or board/<CONFIG_SYS_BOARD> directory is compiled depending on
+         whether CONFIG_SYS_VENDOR is set or not.
+
+         This is optional.  For those targets without the board directory,
+         leave this option empty.
+
+config SYS_CONFIG_NAME
+       string
+       help
+         This option should contain the base name of board header file.
+         The header file include/configs/<CONFIG_SYS_CONFIG_NAME>.h
+         should be included from include/config.h.
