arm64: dts: exynos: gs101: use correct clocks for usi_uart

Wrong pclk clocks have been used in this usi_uart instance here. 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.
