disk: introduce get_device()
This patch introduces function get_device(). This looks up a block_dev_desc_t from an interface name (e.g. mmc) and device number (e.g. 0). This function is essentially the non-partition-specific prefix of get_device_and_partition(). Signed-off-by: Stephen Warren <swarren@nvidia.com>
