drivers: display: ili9xxx: add tearing effect support

Add tearing effect support for better display synchronization. If
tearing effect is configured in the mipi_dbi device, the display
controller configures its tearing effect register.
Display orientation configuration is updated to also rotated the
direction of the display pixel vertical scanline, such that scan order
matches the display orientation.
