mb/google/kukui: fix screen scrolling on devices using anx7625
anx7625 enables MIPI receiver to check EOTP packet as default.
If MIPI_DSI_MODE_EOT_PACKET is not set in flags, soc dsi will not
send out EOTP packet and some panel models will display abnormal
such as scrolling all the time.
BUG=b:144824303
BRANCH=kukui
TEST=boot damu board, edp panel with anx7625 as bridge boots up
without scrolling.
