ARM: dts: qcom: Add SDX65 platform and MTP board support

Add basic devicetree support for SDX65 platform and MTP board from
Qualcomm. The SDX65 platform features an ARM Cortex A7 CPU which forms
the Application Processor Sub System (APSS) along with standard Qualcomm
peripherals like GCC, TLMM, BLSP, QPIC, and BAM etc... Also, there
exists the networking parts such as IPA, MHI, PCIE-EP, EMAC, and Modem
etc..

This commit adds basic devicetree support that includes GCC, RPMh clock, INTC
and Debug UART.
