drm/dp: Implement I2C_M_STOP for i2c-over-aux

Browse source

Consult the I2C_M_STOP flag to determine whether to set the MOT bit or
not. Makes it possible to send multiple messages in one go with
stop+start generated between the messages (as opposed nothing or
repstart depending on whether thr address/rw changed).

Not sure anyone has actual use for this but figured I'd handle it
since I started to look at that flag for MST remote i2c xfers.
