sub device info
Sub-device is the concept basing on the "device" behind "vaDisplay".
If a device could be divided to several sub devices, the task of
decode/encode/vpp could be assigned on one sub-device. So, application
could choose the sub device before any other operations. After that,
all of the task execution/resource allocation will be dispatched to
the sub device. If application does not choose the sub device, driver
will assign one as default.
If the value == VA_ATTRIB_NOT_SUPPORTED, it mean that the attribute
is unsupport or UNKNOWN.
