usb: dwc3: core: Fix compile warning on s390 gcc in dwc3_get_phy call

Recent commit introduced support for reading Multiport PHYs and
while doing so iterated over an integer variable which runs from
[0-254] in the worst case scenario. But S390 compiler treats it as a
warning and complains that the integer write to string can go to 11
characters. Fix this by modifying iterator variable to u8.
