Place analog i2c master control functions (e.g. regi2c_ctrl_read_reg, regi2c_ctrl_write_reg) into IRAM,
so that these functions can be IRAM-safe and able to be called in the other IRAM interrupt context.

If enabled, this option will perform additional checks on modem clock configuration
to ensure proper operation and detect potential configuration issues.
