Kconfig: Move CONFIG_FIT and related options to Kconfig

Browse Source 
There are already two FIT options in Kconfig but the CONFIG options are
still in the header files. We need to do a proper move to fix this.

Move these options to Kconfig and tidy up board configuration:

   CONFIG_FIT
   CONFIG_OF_BOARD_SETUP
   CONFIG_OF_SYSTEM_SETUP
   CONFIG_FIT_SIGNATURE
   CONFIG_FIT_BEST_MATCH
   CONFIG_FIT_VERBOSE
   CONFIG_OF_STDOUT_VIA_ALIAS
   CONFIG_RSA

Unfortunately the first one is a little complicated. We need to make sure
this option is not enabled in SPL by this change. Also this option is
enabled automatically in the host builds by defining CONFIG_FIT in the
image.h file. To solve this, add a new IMAGE_USE_FIT #define which can
be used in files that are built on the host but must also build for U-Boot
and SPL.

Note: Masahiro's moveconfig.py script is amazing.

WARNING: When relying on signed FIT images with a required signature
check the legacy image format is disabled by default, so that
unsigned images cannot be loaded. If a board needs the legacy image
format support in this case, enable it using
CONFIG_IMAGE_FORMAT_LEGACY.
config FIT_BEST_MATCH
bool "Select the best match for the kernel device tree"
depends on FIT
help
When no configuration is explicitly selected, default to the
one whose fdt's compatibility field best matches that of
U-Boot itself. A match is considered "best" if it matches the
most specific compatibility entry of U-Boot's fdt's root node.
The order of entries in the configuration's fdt is ignored.
config FIT_VERBOSE
bool "Show verbose messages when FIT images fails"
depends on FIT
help
Generally a system will have valid FIT images so debug messages
are a waste of code space. If you are debugging your images then
you can enable this option to get more verbose information about
failures.
config OF_BOARD_SETUP
bool "Set up board-specific details in device tree before boot"
depends on OF_LIBFDT
help
This causes U-Boot to call ft_board_setup() before booting into
the Operating System. This function can set up various
board-specific information in the device tree for use by the OS.
The device tree is then passed to the OS.
config OF_SYSTEM_SETUP
bool "Set up system-specific details in device tree before boot"
depends on OF_LIBFDT
help
This causes U-Boot to call ft_system_setup() before booting into
the Operating System. This function can set up various
system-specific information in the device tree for use by the OS.
The device tree is then passed to the OS.
config OF_STDOUT_VIA_ALIAS
bool "Update the device-tree stdout alias from U-Boot"
depends on OF_LIBFDT
help
This uses U-Boot's serial alias from the aliases node to update
the device tree passed to the OS. The "linux,stdout-path" property
in the chosen node is set to point to the correct serial node.
This option currently references CONFIG_CONS_INDEX, which is
incorrect when used with device tree as this option does not
exist / should not be used.
