drm: mxsfb: Select DRM_PANEL

Select DRM_PANEL, since the MXSFB driver depends on it. Otherwise,
we get the following error when compiling:

drivers/built-in.o: In function `mxsfb_probe':
core.c:(.text+0x9ce9c): undefined reference to `drm_panel_attach'
core.c:(.text+0x9cff0): undefined reference to `drm_panel_detach'
drivers/built-in.o: In function `mxsfb_panel_connector_destroy':
