Carve out function size_check from macro BOARD_SIZE_CHECK. This will allow us to reuse the function for other file size checks.
Depending on the value of CONFIG_BOARD_SIZE_LIMIT an error like the following is thrown:
u-boot-dtb.img exceeds file size limit: limit: 409516 bytes actual: 444346 bytes excess: 34830 bytes make: *** [Makefile:1212: u-boot-dtb.img] Error 1
