platform: msm_shared: cleanup register programming of EOT_PACKET_CTRL

The current register programming logic of EOT_PACKET_CTRL can cause
issues for video mode panels where tx_eot_append bit that gets
programmed during mdss_dsi_host_init gets reset to 0x0 during
mdss_dsi_video_mode_config. For command mode panels, EOT_PACKET_CTRL
is being programmed to 0x1 always. Also, rx_eot_append bit programming
is not taken care at present. Cleanup the register programming of
EOT_PACKET_CTRL to take care of this.
