* Initialize the ICG map of some modem clock domains in the PMU_ACTIVE state

* MODEM_APB, I2C_MST and LP_APB clock domains in the PMU_ACTIVE state, and
* disable the clock gating of these clock domains in the PMU_ACTIVE state,
* because the system clock source (PLL) in the system boot up process needs
* to use the i2c master peripheral.
*
* ICG map of all modem clock domains under different power states (PMU_ACTIVE,
* PMU_MODEM and PMU_SLEEP) will be initialized in esp_perip_clk_init().
