Port Disable Self-Powered: Disables 1 or more ports.
0 = Port is available
1 = Port is disabled
During self-powered operation when mapping mode is disabled
(PRTMAP_EN='0'), this selects the ports which will be permanently disabled,
and are not available to be enabled or enumerated by a host controller. The
ports can be disabled in any order, the internal logic will automatically report
the correct number of enabled ports to the USB host, and will reorder the
active ports in order to ensure proper function.
When using the internal default option, the PRT_DIS_P[x:1] and
PRT_DIS_M[x:1] pins will disable the appropriate ports.
