stm32: exti: define AFIO/SYSCFG_EXTICR_FIELDSIZE for all chip.

Browse Source 
While on all current chips, exticr gpio port mux selection is coded on 4 bits,
stm32g0 EXTI_EXTICR register uses 8 bits.  Align all exti header to reference
that value (was previously defined for f0 as SYCFG_EXTICR_SKIP)
