arm: Update dts to work with the new HDLCD driver

Browse source 
The dts files in system/arm/dt currently assume that an (unreleased)
gem5-specific virtual encoder is used as a remote endpoint for the
HDLCD. This driver won't be released as a more general virtual encoder
is about to be posted on the Linux DRI devel list and this encoder has
now been merged with gem5's kernel tree. This changeset updates gem5's
dts files to use that encoder.
