realtek: dts: fix SKS8300-8T i2c0 cells

The build system currently issues the following warnings.

../dts/rtl9303_xikestor_sks8300-8t.dts:57.4-17: Warning (reg_format):
/switchcore@1b000000/i2c@36c/i2c@0/temperature-sensor@48:reg: property
has invalid length (4 bytes) (#address-cells == 2, #size-cells == 1)

Fix that by providing proper cell data.
