colibri_vf: fixup DT with DDR property to support LPSTOP
Fixup the device-tree with the property fsl,has-cke-reset-pulls
which annotates that the board has pull-ups/downs which are required
to put the memory into self-refresh mode. The self-refresh mode in
turn is a requirement to put the SoC into deep sleep mode LPSTOP.
