Kernel/USB: Replace PortNumber enum with a raw u8
A hub can technically have up to 255 ports, given that bNbrPorts is a
u8 and the DeviceRemovable field is a VLA to support up to 255 ports.
Source: USB 2.0 Specification Section 11.23.2.1
That means this enum is not going to scale well in terms of size.
Replacing it with a raw u8 allows me to remove the two port assumption
and a cast.
