arm64: errata: Add QCOM_KRYO_4XX_GOLD to the spectre_bhb_k24_list

Qualcomm Kryo 400-series Gold cores have a derivative of an ARM Cortex
A76 in them. Since A76 needs Spectre mitigation via looping then the
Kyro 400-series Gold cores also need Spectre mitigation via looping.

Qualcomm has confirmed that the proper "k" value for Kryo 400-series
Gold cores is 24.
