* @brief Calculate and set APLL coefficients by given frequency
* @note Have to call 'periph_rtc_apll_acquire' to enable APLL power before setting frequency
* @note This calculation is based on the inequality:
* xtal_freq * (4 + sdm2 + sdm1/256 + sdm0/65536) >= SOC_APLL_MULTIPLIER_OUT_MIN_HZ(350 MHz)
* xtal_freq * (4 + sdm2 + sdm1/256 + sdm0/65536) >= CLK_LL_APLL_MULTIPLIER_MIN_HZ(350 MHz)
* It will always calculate the minimum coefficients that can satisfy the inequality above, instead of loop them one by one.
* which means more appropriate coefficients are likely to exist.
* But this algorithm can meet almost all the cases and the accuracy can be guaranteed as well.
