drm/tinydrm: Move tinydrm_display_pipe_init() to mipi-dbi

tinydrm_display_pipe_init() has only one user now, so move it to mipi-dbi.

Changes:
- Remove drm_connector_helper_funcs.detect, it's always connected.
- Store the connector and mode in mipi_dbi instead of it's own struct.

Otherwise remove some leftover tinydrm-helpers.h inclusions.
