[ Upstream commit d355c895fa4ddd8bec15569eee540baeed7df8c5 ]
The RTC and RTT peripherals use the timing domain slow clock (TD_SLCK), sourced from the 32.768 kHz crystal oscillator or slow rc oscillator.
The previously used Monitoring domain slow clock (MD_SLCK) is sourced from an internal RC oscillator which is most probably not precise enough for real time clock purposes.
