Add GYRO_1_CLKIN_PIN to TIMER_PIN_MAPPING.
The configuration defines USE_GYRO_CLKIN and GYRO_1_CLKIN_PIN PB14, but TIMER_PIN_MAPPING contains no entry for that pin. Without a timer entry, the firmware cannot generate the 32 kHz clock, and the gyro runs without the external clock.
Add an entry with the correct timer occurrence for PB14 and DMA index -1. PB14 on STM32H743 maps to TIM1_CH2N, TIM8_CH2N, and TIM12_CH1. Select the occurrence that corresponds to TIM12_CH1, because complementary channels are not suitable here.
Based on learnings: "when GYRO_1_CLKIN_PIN (or GYRO_2_CLKIN_PIN) is defined, it must be included in the TIMER_PIN_MAPPING with appropriate timer and DMA settings, typically with DMA index -1."
🐛 Proposed addition (confirm the occurrence index against `timer_stm32h7xx.c`)
TIMER_PIN_MAP( 8, MOTOR8_PIN, 1, 4)

Correct the timer occurrences and add the gyro clock pin.
Use occurrence 1 for PD12, PB4, PB5, PE9, PE11, PE13, and PE14. Use occurrence 2 for PB0 and PB1. Add GYRO_1_CLKIN_PIN (PB14) with occurrence 2 and DMA option -1; this selects non-complementary TIM12_CH1.
Do not require globally unique DMA option values.
