arm64: dts: amlogic: meson-g12: Fix GPU operating point table node name

[ Upstream commit bb98a6fd0b0e227cefb2ba91cea2b55455f203b7 ]

Starting with commit 94274f20f6bf ("dt-bindings: opp: Convert to DT
schema") the opp node name has a mandatory pattern. This change
fixes the dtbs_check warning:
gpu-opp-table: $nodename:0: 'gpu-opp-table' does not match
'^opp-table(-[a-z0-9]+)?$'
Put the 'gpu' part at the end to match the pattern.

Fixes: 916a0edc43f0 ("arm64: dts: amlogic: meson-g12: add the Mali OPP table and use DVFS")
