Device tree alignment with Linux kernel v5.17-rc1
- ARM: dts: stm32: add pull-up to USART3 and UART7 RX pins
  on STM32MP15 DKx boards
- ARM: dts: stm32: clean uart4_idle_pins_a node for stm32mp15
- ARM: dts: stm32: tune the HS USB PHYs on stm32mp15xx-dkx
- ARM: dts: stm32: tune the HS USB PHYs on stm32mp157c-ev1
- ARM: dts: stm32: fix stusb1600 pinctrl used on stm32mp157c-dk
