Subject: [PATCH 9/9] ARM: dts: stm32: adapt i2s node to spi binding on stm32mp15xx-dk

In DT check utility, the spi2s2 node is identified as an spi node.
The check_spi_bus_reg() function issues a warning "missing or empty
reg property" if reg property is not defined in child nodes.
Add reg property to STM32 I2S port node on STM32MP15XX-DK board
to match this requirement and add related unit-address in node name.
