Unlike other Qcom SoCs, IPQ5424 doesn't have multiple instances
of LLCC IP and hence doesn't have a LLCC_BROADCAST register
space, and the LLCC & LLCC_BROADCAST point to the same register
space.

Alter the driver accordingly and add the relevant entries for
enabling LLCC/system-cache-controller on the Qcom IPQ5424 SoC.

Depends On:
https://lore.kernel.org/linux-arm-msm/20241028060506.246606-1-quic_srichara@quicinc.com/

---
v3:	Rebase to ToT
	Remove 'need_llcc_config = true'

v2:	Add reviewed-by for dt-bindings and dts patches
	Add 'no_broadcast_register' to identify SoC without LLCC_BROADCAST register space

v1:	https://lore.kernel.org/linux-arm-msm/20241104073840.3686674-1-quic_varada@quicinc.com/
