[U-Boot] [PATCH 08/27] ARM64: zynqmp: DT: Remove unused DDR PM domain

From: Filip Drazic <filip.drazic at aggios.com>

DDR power states are handled by the PM firmware, so this domain is
redundant. Also, since there is no device using this PM domain,
it will be powered off during boot, which is wrong.
