From: Sricharan Ramabadhran <quic_srichara@quicinc.com>

Add initial device tree support for the Qualcomm IPQ5424 SoC and
rdp466 board.

Signed-off-by: Sricharan Ramabadhran <quic_srichara@quicinc.com>
---
  [v2] Sorted nodes based on address, fixed labels case.
       Removed CPU_MASK for all nodes
       Dropped the chosen node
       Removed the redundant 'status=okay', ordered clocks
       child nodes alphabetically.
