Document the Last Level Cache Controller on IPQ5424. The 'broadcast' register space is present only in chipsets that have multiple instances of LLCC IP. Since IPQ5424 has only one instance, both the LLCC and LLCC_BROADCAST points to the same register space. Hence, allow only '1' reg & reg-names entry for IPQ5424.
