board: zynqmp: zynqmp-sm-k26-revA: release DP from reset
This releases the DP configuration from reset early on during the boot process
for K26 SOM. It will also avoid the boot hang situation should any attempt be
made to configure the DP registers while it is still in reset.
Fixes the same issue as described by the commit 8b81010a2fe3 ("video:
zynqmp: Add support for reset").
