stm32h7 stm32h7: compile with stm32_rcc.c stm32h7: some PWR definitions stm32h7: add some RCC defs and change some code style to be more like in other STM ports stm32h7: basic clocks configuration Approved-by: GregoryN <gnutt@nuttx.org>
See configs/nucleo-h743zi/README.txt for a detailed description of the state of the port.
