PATCH v2 1/1 common: env: support sata device

Introduce env support for sata device.
1. Implement write_env/read_env/env_relocate_spec/saveenv/sata_get_env_dev
2. If want to enable this feature, define CONFIG_ENV_IS_IN_SATA, and define CONFIG_SYS_SATA_ENV_DEV or implement your own sata_get_ev_dev.
