[PATCH 3/5] arm64: dts: exynos: gs101: use correct clocks for usi8

Wrong pclk clocks have been used in this usi8 instance here. For USI
and I2C, we need the ipclk and pclk, where pclk is the bus clock.
Without it, nothing can work.
It is unclear what exactly is using USI8_USI_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 i2c drivers.

Update the DTSI accordingly.

Fixes: 6d44d1a1fb62 ("arm64: dts: exynos: gs101: define USI8 with I2C configuration")
