bsp/lpcxpresso55s28: Call FLASH_Init before FFR_Init
hal_bsp_init() called FFR_Init() with zeroed flash_config_t. ROM FFR
functions use flash geometry that is filled in by FLASH_Init(), so
later hal_bsp_hw_id() -> FFR_GetUUID() ended in divide by zero usage
fault inside ROM. This happens to any application that reads hardware
id, e.g. USB network glue that derives MAC address from it.
Call FLASH_Init() on the same config before FFR_Init() as NXP SDK
drivers do.
