env: add prototypes for weak function
This patch adds prototypes for several weak functions: - env_ext4_get_intf - env_ext4_get_dev_part - env_get_location It solves the following warnings when compiling with W=1 on stm32mp1 board: board/st/stm32mp1/stm32mp1.c:849:19: warning: no previous prototype for 'env_get_location' [-Wmissing-prototypes] enum env_location env_get_location(enum env_operation op, int prio) ^~~~~~~~~~~~~~~~ board/st/stm32mp1/stm32mp1.c:876:13: warning: no previous prototype for 'env_ext4_get_intf' [-Wmissing-prototypes] const char *env_ext4_get_intf(void) ^~~~~~~~~~~~~~~~~ board/st/stm32mp1/stm32mp1.c:889:13: warning: no previous prototype for 'env_ext4_get_dev_part' [-Wmissing-prototypes] const char *env_ext4_get_dev_part(void) ^~~~~~~~~~~~~~~~~~~~~ Signed-off-by: Patrice Chotard <patrice.chotard@st.com> Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>
