dts/arm/st: Add stm32u5 base and initial device Add initial basic description for Cortex-M33 based stm32u5 soc series. This encompass description for base nodes, such as: - cpu - flash - clocks - sram Additionally, provide description for variant stm32u575Xi. Related to clocks nodes, added bindings for stm32u5 specific rcc node as well as msi and pll clocks. Header file stm32_clock_control.h was also updated to support these new bindings. Note that for compatibility with existing definitions, clock node describing main pll clock, known as "PLL1", was given two labels: "pll" and "pll1".

dts: stm32: Describe default domain clock configuration for usb devices Describe USB default domain clock on all USB devices. When available select HSI48. On some series, a default clock my be set by default at start up. On those series, in order to be able to compute USB clock at runtime, clock_control driver needs to be aware of configuration and then this default config has to be described explicitly too. Default clocks are not enabled though. It is up to board configuration to provide correct clock configuration (and we should not enabled by default clocks that would not be required by board configuration). Note: This change doesn't consider STM32F1/F3 devices, which have a specific USB clock configuration. Signed-off-by: Erwan Gouriou <erwan.gouriou@linaro.org>
