ASoC: dt-bindings: Fix RT5677 "realtek,gpio-config" type

"realtek,gpio-config" is described as six 8-bit GPIO configuration
values, and the RT5677 driver stores and reads those values as bytes.
The binding incorrectly documented the property as a uint32 array.

Document "realtek,gpio-config" as a uint8-array so the generated
schema matches the hardware definition and the existing driver helper.
