[PATCH v3 15/15] ARM: dts: qcom: Add initial device tree for Kuno SoC

[Hardeep Sharma <hardeep.sharma@oss.qualcomm.com>]

Add SoC-level DTSI (qcom-kuno.dtsi) and IDP board DTS
(qcom-kuno-idp.dts) for the Qualcomm Kuno SoC.

Peripherals included in this initial set:
  - Single Cortex-A7 CPU with PSCI idle states
  - RPMh RSC with clock controller, power domains, and BCM voter
  - GCC (Global Clock Controller)
  - TLMM pin controller (110 GPIOs)
  - Interconnect (aggre-noc, cnoc-main)
  - GENI UART console (QUP SE3)
  - SMEM, hardware spinlocks (TCSR mutex)
