Samsung DTS ARM64 changes for v6.9

Mostly work around Google GS101 SoC and Pixel phone (Oriole) adding
support for:

1. Multi Core Timer (MCT) clocksource.
2. Several clock controllers (DTS and DT bindings) and use new clocks in
   several other device nodes.
3. More serial-interface instances: USI8 and USI12 with I2C.

Exynos850:
1. SPI and DMA controllers (PL330).
