Saranya Gopal df0383ffad usb: typec: ucsi: Add debugfs for ucsi commands 
Add support for UCSI commands through the following debugfs:
  # /sys/kernel/debug/usb/ucsi/$UCSI_DEVICE/command
  # /sys/kernel/debug/usb/ucsi/$UCSI_DEVICE/response

Eg: To execute UCSI GetCapabilities:
  # echo 0x6 > /sys/kernel/debug/usb/ucsi/<ucsi device>/command
Then read the result,
  # cat /sys/kernel/debug/usb/ucsi/<ucsi device>/response
    0x02000320000000020000ff0400000445

UCSI command will be written into the command file and the
response for the command can be viewed under the response file.
