image_classes_dynamic: Support arbitrary address size

Some of our 64bit platforms now have a flash peripheral that resides
outside of the 32bit address space. We now need 9 or more nibbles to
express the size. To better support this, we make the address
replacement dynamic. The lower 7 nibbles of the address (28 bits) are
used for the offset into the flash, while the upper nibbles are used
for the address to the peripheral.

Tested: Built a 7xx and 8xx platform that use dynamic images and
verified manually that their command lines reflect valid flash
addresses.
