bootloader: bl_crypto: Change wrong comments

The comments for no SHA256 and no secp256r1 wrongly stated that these are disabled, this however is not true, the fields are accessed and must still be present, therefore explain that whilst they might not be checked, they are still required to be present Signed-off-by: Jamie McCrae <[email protected]>
