When the startup code initializes RTC_SLOW_CLK, it can perform
calibration by comparing the RTC_SLOW_CLK frequency with main XTAL
frequency. This option sets the number of RTC_SLOW_CLK cycles measured
by the calibration routine. Higher numbers increase calibration
precision, which may be important for applications which spend a lot of
time in deep sleep. Lower numbers reduce startup time.
When this option is set to 0, clock calibration will not be performed at
startup, and approximate clock frequencies will be assumed:
- 150000 Hz if internal RC oscillator is used as clock source. For this use value 1024.
- 32768 Hz if the 32k crystal oscillator is used. For this use value 3000 or more.
In case more value will help improve the definition of the launch of the crystal.
If the crystal could not start, it will be switched to internal RC.

/* Calibration of RTC_SLOW_CLK is performed using a special feature of TIMG0.

* Slow clock calibration feature has two modes of operation: one-off and cycling.
* In cycling mode (which is enabled by default on SoC reset), counting of XTAL

* enabled using TIMG_RTC_CALI_START bit.
