clk: samsung: exynos850: Implement CMU_CMGP domain

Browse Source 
CMU_CMGP clock domain provides clocks for CMGP IP-core (Common GPIO).
CMGP module encapsulates next blocks:
  - 8 GPIO lines
  - 1 GPADC
  - 2 USI blocks, each can be configured to provide one of
    UART/SPI/HSI2C serial interfaces
