zephyr: Fix csp_bin_sem signatures and introduce csp_bin_sem_init()
zephyr: Fix csp_bin_sem signatures and introduce csp_bin_sem_init()

The commit a667c90a8087f and 6be3fb14d50222 changed the function
signatures of csp_bin_sem.  Fix Zephyr's by replacing
csp_bin_sem_handle_t to csp_bin_sem_t.

These changes replace csp_bin_sem_create_static() with
csp_bin_sem_init() as well.
