Marek Vasut f40c2281d2 drm: mxsfb: Fix NULL pointer dereference crash on unload 
commit 3cfc183052 upstream.

The mxsfb->crtc.funcs may already be NULL when unloading the driver,
in which case calling mxsfb_irq_disable() via drm_irq_uninstall() from
mxsfb_unload() leads to NULL pointer dereference.

Since all we care about is masking the IRQ and mxsfb->base is still
valid, just use that to clear and mask the IRQ.

Fixes: ae1ed00932 ("drm: mxsfb: Stop using DRM simple display pipeline helper")
