DP Altmode DFP: Add `mfallow` command
The USB Type-C Altmode allows for protocols other than USB to be
transferred over a USB connection. Chromebooks use this functionality to
transfer DisplayPort on USB signals. This is achieved through USB-PD
handshake through SVDMs to discover, configure, and to enter or exit Alt
modes. When DisplayPort as an Alt Mode is enabled, allowable
functionalities are:
-- SS and high speed USB functionality and two-lane DP.
-- HS USB functionality and 4-lane DP.
Chromebooks honor Multifunction bit set in the DPStatus message sent by
a dock. However, for development purposes we would like to have control
to honor the MF bit or ignore it, there by achieving 2-lane DP vs 4-lane
DP functionality. 4-lane DP functionality is required to test higher
resolution monitors such as 4k60.
BUG=b:181365633
BRANCH=none
TEST=make BOARD, tested on G5 dock with kindred.
