[U-Boot] [PATCH 07/11] env: gd flags without ENV_READY is enough to discriminate in

[Quentin Schulz]

env_get_default

To prepare the removal of env_valid in an upcoming patch, and since the
ENV_READY flag in gd is enough to discriminate in env_get_char, let's
update env_get_char to return the variable in the default environment
when ENV_READY flag is not set and remove env_valid setting and getting
from env_get_default.
