imx-drm: fixes for parallel-display, imx-tve, and ipu-common

These patches fix the parallel-display driver to use the standard OF
graph bindings for connecting a drm_panel via device tree instead of
an undocumented, driver specific device tree property, take care to
disable all IPU interrupts before setting up the irq chip to fix a
kexec lockup, and fix VGA output on i.MX53-QSB boards by correcting
the media bus format set by the imx-tve driver.
