Qualcomm IPQ9650 is a networking SoC targeted at routers, gateways, and
access points. This change adds minimal support required to boot the
IPQ9650 RDP488 board.
Compared to earlier IPQ SoCs, IPQ9650 features a heterogeneous CPU
configuration with four Cortex-A55 cores and one Cortex-A78 core, a
2 MB shared L3 cache, SMMU support, IPCC, five PCIe Gen3 controllers,
an integrated CDSP for task offloading, enhanced PPE capabilities,
and DDR5 memory support.

Changes in v3:
- Added \n before the status property
- Rebased on next-20260507
- Dropped the REFGEN, PRIMESS clocks from the bindings and the GCC
driver since the ownership of these clocks are in discussion. It will
be added back if Linux needs to play with those clocks.
- Link to v2:

Changes in v2:
- Collected the R-b tags
- Add the ARM64 dependency to the GCC driver and enable it by default to
align with Krzysztof's effort to cleanup the defconfig
- Updated the GICv3 interrupt-cells to 4 and added the ppi-partitions
and hooked up with the PMU instances.
- Made the labels to lower case and kept the \n before status property
- Dropped the defconfig patch
- Link to v1: https://patch.msgid.link/20260415-ipq9650_boot_to_shell-v1-0-b37eb4c3a1d1@oss.qualcomm.com
