commit 132dc4fe5b587c0a62fc90d78e7413944fa06669

wifi: rtw89: 8852b: add chip_ops to read efuse
efuse stores individual data about a chip itself, such as MAC address,
country code, RF and crystal calibration data, and so on. Define a struct
to help access efuse content, and copy them into a common struct.
