Fix settings for TEAR and DPHYCMD0 to match initialization data
provided by MCUX SDK driver. The following fixes were needed:
- Tear effect signal should only be sent at the VBLANK interval, so TEON
should be set to 0x0
- DPHYCMD0 LP-RX VHYS trimming was incorrectly being set to 37mV, when
it should be set to 66mV (the default value)
These changes resolve some flickering and blooming that occasionally
occurred during initialization
