OMAP: DSS2: PicoDLP: fix error handling in power_on
Fix two problems in PicoDLP driver's error handling on
picodlp_panel_power_on:
- If omapdss_dpi_display_enable() failed, the its error value was not
returned
- If picodlp_i2c_init() failed, dssdev->state was erroneously set to
OMAP_DSS_DISPLAY_ACTIVE
