dt-bindings: fix warnings in xinpeng,xpp055c272.yaml

The reg property in the example caused following warnings:

xinpeng,xpp055c272.example.dts:20.17-27: Warning (reg_format): /example-0/dsi@ff450000/panel@0:reg: property has invalid length (4 bytes) (#address-cells == 2, #size-cells == 1)

xinpeng,xpp055c272.example.dt.yaml: Warning (pci_device_bus_num): Failed prerequisite 'reg_format'
xinpeng,xpp055c272.example.dt.yaml: Warning (i2c_bus_reg): Failed prerequisite 'reg_format'
xinpeng,xpp055c272.example.dt.yaml: Warning (spi_bus_reg): Failed prerequisite 'reg_format'
xinpeng,xpp055c272.example.dts:18.21-24.15: Warning (avoid_default_addr_size): /example-0/dsi@ff450000/panel@0: Relying on default #address-cells value
xinpeng,xpp055c272.example.dts:18.21-24.15: Warning (avoid_default_addr_size): /example-0/dsi@ff450000/panel@0: Relying on default #size-cells value

Added #address-cells and #size-cells to silence the warning.
