PWIDTH
Indicates the port width modes supported by the port
0b00 = No support for 2x or 4x
0b01 = No support for 2x; support for 4x
0b10 = Support for 2x; no support for 4x
0b11 = Support for 2x and 4x
Note: 1x is supported by all ports.
Note: The definition of 0b01 and 0b10 is consistent with the
RapidIO Specification (Rev. 2.0). This definition is incompatible
with the RapidIO Specification (Rev. 1.3) and earlier
specifications, and is incompatible with the RapidIO Specification
(Rev. 2.1) and later specifications.
