rapidio: add definitions of Component Tag fields

Add definition of the unique device identifier field in the component tag.
 RIO_CTAG_UDEVID does not take all 32 bits of the component tag value to
allow future extensions to the component tag use.

Selected size of the RIO_CTAG_UDEVID field (17 bits) is sufficient to
accommodate maximum number of endpoints in large RIO network (16-bit id)
plus switches.
