usb: TOSHIBA Disk Can't Be Recognized on the Port of USB 2.0 [1/1]

PD#SWPL-14156

Problem:
TOSHIBA Disk can't be recognized on the Port of USB 2.0 and since then
any disk can't be recognized.This is because
that the CCS flag of the PORTSC is still set and if write 0
to 0x38 of usb phy register the CCS will change to
0 and so that other disks can be recognized.

Solution:
when the enumeration fails, call set_usb_phy_host_tuning.

Verify:
test pass on u212
