xhci: Adjust the UHCI Controllers bit value 

zhaoxin inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I40QDN


CVE: NA

----------------------------------------------------------------

Over Current condition is not standardized in the UHCI spec.
Zhaoxin UHCI controllers report Over Current active off.
Intel controllers report it active on, so we'll adjust the bit value.
