env: unify logic to check and apply changes
The logic of checking special parameters (e.g. baudrate, stdin, stdout, for a valid value and/or whether can be overwritten) and applying the new value to the running system is now all within a single function env_check_apply() which can be called whenever changes are made to the environment, no matter if by set, default or import. With this patch env_check_apply() is only called by "env set", retaining previous behavior. Signed-off-by: Gerlando Falauto <gerlando.falauto@keymile.com> Reviewed-by: Marek Vasut <marex@denx.de>
