f4fcf5d6eb dm: virtio: remove hv_caps from virtio_ops 
currently, each virtio device has their own virtio_ops implementation.
Take virtio-blk for example:

static struct virtio_ops virtio_blk_ops = {
        "virtio_blk",
        1,
        sizeof(struct virtio_blk_config),
        virtio_blk_reset,
        virtio_blk_notify,
        virtio_blk_cfgread,
        virtio_blk_cfgwrite,
        NULL,
        NULL,
        VIRTIO_BLK_S_HOSTCAPS,
};

If start DM with two virtio-blk, this global variable will be
assigined to two virtio-blk instances. Changing hv_caps for one
instance will affect others. But different instances may need
different capabilities.

To support this requirement, we suggest to move hv_caps to
virtio_base structure, and each instance can return their own
capabilities.

8db85ecb25 DM: RPMB virtualization 
Full logic to supprot vRPMB:
1. Automatic switch between physical or simulated RPMB.
   But hardcode to use simulated one.
2. Parse RPMB cmd to basic APIs to:
   2.1 check request frame HMAC with uos vkey
   2.2 replace RPMB frame with real values.
3. RPMB partitioning for multiple UOS.
   It's hardcoded for coming config file support.

6c4ebe3f26 VRPMB-BE: create virtio rpmb backend VBS-U 
This patch implements virtio rpmb backend VBS-U component,
it includes the basic module interface with DM. This
component will work with vRPMB FE driver together to
provide one communication channel between UOS and SOS.
