[U-Boot] [PATCH 2/2] env: Add back default action of get_char in env_get_char()

[York Sun]

Commit 8a3a7e2270b3 ("env: Pass additional parameters to the env
lookup function") dropped the default action if driver doesn't have
get_char() defined. This causes failure to get environmental
variables from NOR flash. Add back this default action for now.
