This is a prep work commit for adding flash page layout support. The internal flash APIs for STM32 on L4 and F4 are a bit inconsistent. Some routines take a pointer to the private data, others don't. Those that do take it as a last argument instead of a first. Additionally, some APIs are declared in flash_stm32.h that aren't ever used by the family-specific files. Clean this up by making everything take a struct device*, and marking routines static in the common driver code when possible. Signed-off-by: Marti Bolivar <marti.bolivar@linaro.org>
