sbus: Add prototype for bbc_envctrl_init and bbc_envctrl_cleanup to header

Browse Source 
This fixes the following build warning:

	drivers/sbus/char/bbc_envctrl.c:566:5: error: no previous prototype for ‘bbc_envctrl_init’ [-Werror=missing-prototypes]
	  566 | int bbc_envctrl_init(struct bbc_i2c_bus *bp)
	      |     ^~~~~~~~~~~~~~~~
	drivers/sbus/char/bbc_envctrl.c:594:6: error: no previous prototype for ‘bbc_envctrl_cleanup’ [-Werror=missing-prototypes]
	  594 | void bbc_envctrl_cleanup(struct bbc_i2c_bus *bp)
	      |      ^~~~~~~~~~~~~~~~~~~

which in the presence of -Werror=missing-prototypes yields a compiler
error.
