Merge branches 'clk-zynq', 'clk-xilinx' and 'clk-stm' into clk-next

 - Update Zynqmp driver for Versal NET platforms
 - Add clk driver for Versal clocking wizard IP

* clk-zynq:
  drivers: clk: zynqmp: update divider round rate logic
  drivers: clk: zynqmp: calculate closest mux rate

* clk-xilinx:
  clocking-wizard: Add support for versal clocking wizard
  dt-bindings: clock: xilinx: add versal compatible

* clk-stm:
  dt-bindings: stm32: add clocks and reset binding for stm32mp25 platform
  clk: stm32mp1: use stm32mp13 reset driver
  clk: stm32mp1: move stm32mp1 clock driver into stm32 directory
