uadk_cipher: hardware platform checking shouldn't exist in UADK-Engine layer

[docularxu]

Currently, in uadk_cipher.c, there is a checking about the underlining hardware platform (Kunpeng920 or Kunpeng930). From a software design view point, such hardware platform checking should be done in lower layers, such as UADK layer. And in UADK Engine, only the available cipher methods are registered.

Refer to uadk_cipher.c

cipher_930_nids[]


static int uadk_get_accel_platform(char *alg_name)
{
	struct uacce_dev *dev;

	dev = wd_get_accel_dev("cipher");
	if (dev == NULL)
		return 0;

	if (!strcmp(dev->api, "hisi_qm_v2"))
		platform = KUNPENG920;
	else
		platform = KUNPENG930;
	free(dev);

	return 1;
