[PATCH v4 13/22] spl: Tidy up load address in spl_ram

[Simon Glass]

This CONFIG is used but is not given a value by some boards. Use
a default value of 0 explicitly, rather than relying on the 0 value
provided by CONFIG_SPL_LOAD_FIT_ADDRESS

This will allow us to make SPL_LOAD_FIT_ADDRESS depend on SPL_LOAD_FIT
as it should.
