Add clock management unit nodes for:
- cmu_top, which provides muxes, divs and gates for other CMUs
- cmu_peris, which provides clocks for GIC and MCT
- cmu_fsys0, which provides clocks for USBDRD30
- cmu_fsys1, which provides clocks for MMC, UFS and PCIE
- cmu_peric0, which provides clocks for UART_DBG, USI00 ~ USI03
- cmu_peric1, which provides clocks for SPI_CAM0/1, UART_BT,
USI04 ~ USI13
