[PATCH v5 0/5] Add initial support for QCS615 SoC and QCS615 RIDE board

[Lijuan Gao <quic_lijuang@quicinc.com>]

Introduces the Device Tree for the QCS615 platform.

Features added and enabled:
- CPUs with PSCI idle states
- Interrupt-controller with PDC wakeup support
- Timers, TCSR Clock Controllers
- Reserved Shared memory
- QFPROM
- TLMM
- Watchdog
- RPMH controller
- Sleep stats driver
- Rpmhpd power controller
- Interconnect
- GCC and Rpmhcc
- QUP with Uart serial support

Bindings and base Device Tree for the QCS615 SoC are splited
in four parts:
- 1-2: Binding files for QCS615 SoC and PDC (Reviewed)
- 3-4: Initial DTSI and RIDE board device tree
- 5  : Enable uart related configs

- Successfully passed dtbs_check with W=1 for dts
- Verified CPU Hotplug, idle and online CPUs on QCS615 ride board
- Checked pinctrl-maps path
- Verified watchdog functionality with "echo 1 > /dev/watchdog", can trigger
  a watchdog bark and later bite
- Verified functionality with UART console on QCS615 ride board
- RPMH controller driver probed successfully
- Sleep stats driver probed successfully and checked qcom_stats
  node on QCS615 ride board
