This series fixes a reset of state in duplicate state crtc funcs for VOP
driver, a possible crash and ensure crtc reset helper is called in VOP2
driver.

Patch 1 use kmemdup instead of kzalloc to duplicate the crtc state.
Patch 2 change to use crtc and plane cleanup helpers directly.
Patch 3 adds a crash guard for empty crtc state.
Patch 4 adds a missing call to crtc reset helper.

This is the next part of an ongoing effort to upstream HDMI 2.0 support
used in LibreELEC for the past 3+ years.

This series is also available at [1].
