Due to there are some chances USB devices can not be detected.
USB2 port#1 and #4 PHY register need to be overridden.

port#1:
PERPORTPETXISET = 4
PERPORTTXISET = 4
IUSBTXEMPHASISEN= 1
PERPORTTXPEHALF= 0

port#4:
PERPORTPETXISET = 7
PERPORTTXISET = 7
IUSBTXEMPHASISEN= 1
PERPORTTXPEHALF= 0

BUG=b:72623892
BRANCH=master
