Subject: [PATCH 14/38] dt-bindings: media: mediatek,mt8195-jpeg: Allow range number in node address

The dual and triple core jpeg encoder and decoder (respectively)
on MT8195 are far apart: the only way to have this to make sense
is to split those in multiple address ranges in device trees as
one big range would overlap with other IP in at least the MT8195
SoC.

Change both the jpegdec and jpegenc bindings to allow specifying
children nodes such as "jpegdec@0,10000", "jpegdec@1,0" or for
encoder "jpegenc@0,0", "jpegenc@1,0" to resolve dtbs_check issues.
