drm/bridge: synopsys: dw-mipi-dsi: enable EoTp by default 



Enable the transmission of an EoTp (end of transmission packet) by
default. EoTp should be enabled anyway because it is a Linux necessity
that can be disabled by a dsi mod_flag if needed.

EoTp signals the end of an HS transmission, this adds overall robustness
at protocol level at the expense of an increased overhead.
