USB-serial fixes for v4.4-rc3

Here are some device-id fixes that remove a HID device from cp210x, and
adds support for another Infineon flash-loader device. The flash-loader
device presents itself as a CDC-ACM device even though it is clearly
not, so we need to blacklist it in the cdc-acm driver as well.
