drm/bridge: samsung-dsim: fix HFP/HBP/HSA disable modes
The bits in the DSI mode_flags specify that HFP/HBP/HSA should be
disabled/ignored by the controller. This is the same polarity as
the bits in the DSIM control register where a set bit instructs
the controller to ignore the blanking area, so the inversion in
the current code is wrong.
