stm32: exti: stm32g0 have enhanced EXTI_[FR]PR regs instead of EXTIR_PR, use them if defined.

Browse Source 
Make exti_get_flag_status and exti_reset_request use EXTI_RPR and EXTI_FPR if present instead of EXTI_PR.

This is less precise than offered by the RPR/FPR registers, but makes
for a consistent experience in the common API.
