drm/bridge: fsl-ldb: Allow the termination resistor to be enabled
The LVDS Control Register (LVDS_CTRL) register has an HS_EN bit that allows
the 100 Ohm termination resistor in the chip to be enabled.
Add support to setting the HS_EN bit when the optional property
"nxp,enable-termination-resistor" is present.
The motivation for introducing this property was a custom i.MX8MP board
that was showing visual artifacts. After enabling the 100 Ohm termination
resistor the LVDS signal quality improved causing the artifacts to
disappear.
