[PATCH v1 2/3] soc: qcom: llcc: Update configuration data for IPQ5424

[Varadarajan Narayanan <quic_varada@quicinc.com>]

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.
