Samsung DTS ARM64 changes for v6.8

Two (and a half) major items are coming with this pull request:
1. Add specific compatibles to all Samsung Exynos and Tesla FSD blocks,
   because that's what guidelines expect [1] and is generally
   recommended practice.  Existing compatibles are left untouched, thus
   no driver changes are needed.  The work only cleans things up, so any
   future contributions will use recommended style: specific and
   fallback compatibles.

   Since no driver changes are needed in this work and the DTS is
   directly affected by bindings change (running tests with `make
   dtbs_check`), this pull includes all bindings changes, even though
   usual practice is that bindings come via driver subsystem.  Keeping
   everything here makes review and testing easier.  Also will allow us
   to avoid conflicts related to new platforms (see below).

2. Add ExynosAutov920 SoC and SADK board (Samsung Automotive Development
   Kit) with minimal support so far: serial console, GPIO-based keys and
   PWM fan.

3. Add few bindings for upcoming Google GS101 SoC.  This pull request
   does not include its DTS yet, just few reviewed dependencies.  DTS
   will be coming soon.

+
+description: |
+  Google GS101 clock controller is comprised of several CMU units, generating
+  clocks for different domains. Those CMU units are modeled as separate device
+  tree nodes, and might depend on each other. The root clock in that clock tree
+  is OSCCLK (24.576 MHz). That external clock must be defined as a fixed-rate
+  clock in dts.
+
+  CMU_TOP is a top-level CMU, where all base clocks are prepared using PLLs and
+  dividers; all other leaf clocks (other CMUs) are usually derived from CMU_TOP.
+
+  Each clock is assigned an identifier and client nodes can use this identifier
+  to specify the clock which they consume. All clocks available for usage
+  in clock consumer nodes are defined as preprocessor macros in
+  'dt-bindings/clock/gs101.h' header.
