Use proper namespace for the STM32 FDCAN Kconfig symbols, renaming CONFIG_CAN_MAX_STD_ID_FILTER to CONFIG_CAN_STM32_FDCAN_MAX_STD_ID_FILTERS and CONFIG_CAN_MAX_EXT_ID_FILTER to CONFIG_CAN_STM32_FDCAN_MAX_EXT_ID_FILTERS. This prevents Kconfig symbol clashes between different CAN controller drivers. Signed-off-by: Henrik Brix Andersen <henrik@brixandersen.dk>
