For USI and UART, we need the ipclk and pclk, where pclk is the bus clock. Without it, nothing can work. It is unclear what exactly is using USI0_UART_CLK, but it is not required for the IP to be operational at this stage, while pclk is. This also brings the DT in line with the clock names expected by the usi and uart drivers.
