crypto: hisilicon - check _PS0 and _PR0 method
To support runtime PM, use the function 'pci_set_power_state' to change the power state. Therefore, method _PS0 or _PR0 needs to be filled by platform. So check whether the method is supported, if not, print a prompt information. Signed-off-by: Weili Qian <qianweili@huawei.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
