Create board variants like [this](https://github.com/stm32duino/Arduino_Core_STM32/blob/abce8f676b99c2bb53429927b185da74f0c1d1f8/variants/STM32G4xx/G431C(6-8-B)U_G441CBU/variant_B_G431B_ESC1.h#L114) one for each combination of [board layout](https://docs.google.com/spreadsheets/d/15msbDAIMxC2rIkq8Au8vf82ub1qEaS67Lc1cFb86Jpc/edit?usp=sharing) and chip. This could be contributed back to the arduino-gd32 project.
