fix(morello): dts: fix DT node naming

The various official DT bindings only allow certain node name patterns.
Linux' "make dtbs_check" reports:
===========
.../morello-soc.dt.yaml: sram@45200000: 'scp-shmem@0', 'scp-shmem@80' do not match any of the regexes: '^([a-z0-9]*-)?sram(-section)?@[a-f0-9]+$', 'pinctrl-[0-9]+'
   From schema: Documentation/devicetree/bindings/sram/sram.yaml
.../morello-soc.dt.yaml: uart@2a400000: $nodename:0: 'uart@2a400000' does not match '^serial(@.*)?$'
   From schema: Documentation/devicetree/bindings/serial/pl011.yaml
.../morello-soc.dt.yaml: interrupt-controller@2c010000: 'its@30040000', 'its@30060000', 'its@30080000', 'its@300a0000' do not match any of the regexes: '^(msi-controller|gic-its|interrupt-controller)@[0-9a-f]+$', '^gic-its@', '^interrupt-controller@[0-9a-f]+$', 'pinctrl-[0-9]+'
   From schema: Documentation/devicetree/bindings/interrupt-controller/arm,gic-v3.yaml
===========

Rename the node names to improve bindings compliance.
