For some reason we do not really understand, ZTE hardware designers
choose to define PL011 Flag Register bit positions differently from
standard ones as below.
Bit Standard ZTE
-----------------------------------
CTS 0 1
DSR 1 3
BUSY 3 8
RI 8 0
Let's define these bits into vendor data and get ZTE PL011 supported
properly.
