Fix the following DT dtc warnings for stm32h743 boards:
Warning (node_name_chars_strict): /clocks/i2s_ckin: Character '_' not recommended in node name
Warning (unit_address_vs_reg): /memory: node has a reg or ranges property, but no unit name
Warning (unit_address_vs_reg): /soc/pin-controller: node has a reg or ranges property, but no unit name
Warning (unique_unit_address): /soc/pin-controller/i2c1@0: duplicate unit-address (also used in node /soc/pin-controller/usart1@0)
Warning (unique_unit_address): /soc/pin-controller/i2c1@0: duplicate unit-address (also used in node /soc/pin-controller/usart2@0)
Warning (unique_unit_address): /soc/pin-controller/usart1@0: duplicate unit-address (also used in node /soc/pin-controller/usart2@0)
Warning (unique_unit_address): /soc/pin-controller/i2c1@0: duplicate unit-address (also used in node /soc/pin-controller/usbotg-hs@0)
Warning (unique_unit_address): /soc/pin-controller/usart1@0: duplicate unit-address (also used in node /soc/pin-controller/usbotg-hs@0)
Warning (unique_unit_address): /soc/pin-controller/usart2@0: duplicate unit-address (also used in node /soc/pin-controller/usbotg-hs@0)
Warning (unit_address_vs_reg): /soc/pin-controller/usbotg-hs@0: node has a unit name, but no reg property
Warning (avoid_unnecessary_addr_size): /soc/timer@58002c00: unnecessary #address-cells/#size-cells without "ranges" or child "reg" property
Warning (avoid_unnecessary_addr_size): /soc/timer@58003000: unnecessary #address-cells/#size-cells without "ranges" or child "reg" property

IMO, you could used i2c1-0. It will avoid to rewrite this node if new
i2c1 pins groups is added.

clock driver deals with "i2s_ckin" for clock source selection. I need
to check deeper if this change could cause an issue.
thx
