This commit fixes an issue in which boards with FlashIAP block device enabled fails the FlashIAP block device tests exists under the component directory. That's because they have no start address and size configured in the mbed_lib.json file. In order to simplify the test for targets with no definitions in the mbed_lib.json, the test will calculate the start address as the first sector after the application ends and up to the max size available.
