Kconfig: Move autoboot options under boot options

At present the autoboot options are in cmd/Kconfig but they don't really
relate to commands. They relate to booting, so move this menu under the
boot menu.

+config AUTOBOOT
+	bool "Autoboot"
+	default y
+	help
+	  This enables the autoboot.  See doc/README.autoboot for detail.
+
+config AUTOBOOT_KEYED
+	bool "Stop autobooting via specific input key / string"
+	default n
+	help
+	  This option enables stopping (aborting) of the automatic
+	  boot feature only by issuing a specific input key or
+	  string. If not enabled, any input key will abort the
+	  U-Boot automatic booting process and bring the device
+	  to the U-Boot prompt for user input.
+
+config AUTOBOOT_PROMPT
+	string "Autoboot stop prompt"
+	depends on AUTOBOOT_KEYED
+	default "Autoboot in %d seconds\\n"
+	help
+	  This string is displayed before the boot delay selected by
+	  CONFIG_BOOTDELAY starts. If it is not defined	there is no
+	  output indicating that autoboot is in progress.
+
+	  Note that this define is used as the (only) argument to a
+	  printf() call, so it may contain '%' format specifications,
+	  provided that it also includes, sepearated by commas exactly
+	  like in a printf statement, the required arguments. It is
+	  the responsibility of the user to select only such arguments
+	  that are valid in the given context.
+
+config AUTOBOOT_ENCRYPTION
+	bool "Enable encryption in autoboot stopping"
+	depends on AUTOBOOT_KEYED
+	help
+	  This option allows a string to be entered into U-Boot to stop the
+	  autoboot. The string itself is hashed and compared against the hash
+	  in the environment variable 'bootstopkeysha256'. If it matches then
+	  boot stops and a command-line prompt is presented.
+
+	  This provides a way to ship a secure production device which can also
+	  be accessed at the U-Boot command line.
+
+config AUTOBOOT_DELAY_STR
+	string "Delay autobooting via specific input key / string"
+	depends on AUTOBOOT_KEYED && !AUTOBOOT_ENCRYPTION
+	help
+	  This option delays the automatic boot feature by issuing
+	  a specific input key or string. If CONFIG_AUTOBOOT_DELAY_STR
+	  or the environment variable "bootdelaykey" is specified
+	  and this string is received from console input before
+	  autoboot starts booting, U-Boot gives a command prompt. The
+	  U-Boot prompt will time out if CONFIG_BOOT_RETRY_TIME is
+	  used, otherwise it never times out.
+
+config AUTOBOOT_STOP_STR
+	string "Stop autobooting via specific input key / string"
+	depends on AUTOBOOT_KEYED && !AUTOBOOT_ENCRYPTION
+	help
+	  This option enables stopping (aborting) of the automatic
+	  boot feature only by issuing a specific input key or
+	  string. If CONFIG_AUTOBOOT_STOP_STR or the environment
+	  variable "bootstopkey" is specified and this string is
+	  received from console input before autoboot starts booting,
+	  U-Boot gives a command prompt. The U-Boot prompt never
+	  times out, even if CONFIG_BOOT_RETRY_TIME is used.
+
+config AUTOBOOT_KEYED_CTRLC
+	bool "Enable Ctrl-C autoboot interruption"
+	depends on AUTOBOOT_KEYED && !AUTOBOOT_ENCRYPTION
+	default n
+	help
+	  This option allows for the boot sequence to be interrupted
+	  by ctrl-c, in addition to the "bootdelaykey" and "bootstopkey".
+	  Setting this variable	provides an escape sequence from the
+	  limited "password" strings.
+
+config AUTOBOOT_STOP_STR_SHA256
+	string "Stop autobooting via SHA256 encrypted password"
+	depends on AUTOBOOT_KEYED && AUTOBOOT_ENCRYPTION
+	help
+	  This option adds the feature to only stop the autobooting,
+	  and therefore boot into the U-Boot prompt, when the input
+	  string / password matches a values that is encypted via
+	  a SHA256 hash and saved in the environment.
+
+config AUTOBOOT_USE_MENUKEY
+	bool "Allow a specify key to run a menu from the environment"
+	depends on !AUTOBOOT_KEYED
+	help
+	  If a specific key is pressed to stop autoboot, then the commands in
+	  the environment variable 'menucmd' are executed before boot starts.
+
+config AUTOBOOT_MENUKEY
+	int "ASCII value of boot key to show a menu"
+	default 0
+	depends on AUTOBOOT_USE_MENUKEY
+	help
+	  If this key is pressed to stop autoboot, then the commands in the
+	  environment variable 'menucmd' will be executed before boot starts.
+	  For example, 33 means "!" in ASCII, so pressing ! at boot would take
+	  this action.
+
+config AUTOBOOT_MENU_SHOW
+	bool "Show a menu on boot"
+	depends on CMD_BOOTMENU
+	help
+	  This enables the boot menu, controlled by environment variables
+	  defined by the board. The menu starts after running the 'preboot'
+	  environmnent variable (if enabled) and before handling the boot delay.
+	  See README.bootmenu for more details.
