Merge tag 'samsung-dt-bindings-clk-fsd-5.18' into for-v5.18/tesla-fsd

dt-bindings for Tesla FSD clock controllers for 5.18

The Devicetree bindings for Tesla FSD clock controllers.  The bindings
come with a header with clock IDs used by both drivers and DTS.  Merge
them here for the DTS.

description: |
FSD clock controller consist of several clock management unit
(CMU), which generates clocks for various inteernal SoC blocks.
The root clock comes from external OSC clock (24 MHz).
All available clocks are defined as preprocessor macros in
'dt-bindings/clock/fsd-clk.h' header.
