[PATCH v2 16/50] image: Add Kconfig options for FIT in the host build

[Simon Glass]

In preparation for enabling CONFIG_IS_ENABLED() on the host build, add
some options to enable the various FIT options expected in these tools.
This will ensure that the code builds correctly when CONFIG_HOST_xxx
is distinct from CONFIG_xxx.
