arm: dts: dra7-ipu-common-early-boot: Limit IPU early boot to IPU1 only

The dra7-ipu-common-early-boot.dtsi file has the necessary changes to
configure both the IPU1 and IPU2 remote processors for 'early boot' from
SPL. Remove the changes for IPU2 for the moment to limit the 'early boot'
mode for IPU1 _only_. This is being done due to the limitations with some
of the current IPU2 firmware files.
