arm64: dts: exynos: gs101: define all PERIC USI nodes

Universal Serial Interface (USI) supports three types of serial
interface such as UART, SPI and I2C. Each protocol works independently.
USI can be configured to work as one of these protocols. Define all the
USI nodes from the PERIC blocks (USI0-14), in all their possible
configurations. These blocks have the TX/RX FIFO depth of 64 bytes.
