soc/intel : Use 'enum cb_err' values

Use 'enum cb_err' values for below cse lite functions instead of true or
false.

Functions whose return values updated in this patch:
 1. cse_set_next_boot_partition()
 2. cse_data_clear_request()
 3. cse_set_and_boot_from_next_bp()
 4. cse_boot_to_rw()
 5. cse_fix_data_failure_err()

TEST= Do boot test on Gimble.
