ANDROID: db845c fix defconfig to be like .config

Some values in defconfig are set but isn't present in the final .config.
So we change them to be the value in .config.

Fixes the following errors when setting kernel_build(defconfig):

    ERROR: CONFIG_USB_ROLE_SWITCH: actual 'y', expected 'm' from common/arch/arm64/configs/db845c_gki.fragment
    ERROR: CONFIG_QCOM_GLINK_SSR: actual '', expected 'm' from common/arch/arm64/configs/db845c_gki.fragment
    ERROR: CONFIG_MFD_QCOM_QCA639X: actual '', expected 'm' from common/arch/arm64/configs/db845c_gki.fragment
    ERROR: CONFIG_SM_DISPCC_8650: actual '', expected 'm' from common/arch/arm64/configs/db845c_gki.fragment

Bug: 236012223
Test: check that .config does not change before and after this CL.
