Platform: Change flash layout on Musca-A1

- Change the size of an image from 192KB to 1MB in the Musca-A1 flash
layout configuration, and remove the scratch area as it isn't used
(Musca-A1 does not support swapping mode for image upgrade)
- Change the size of the memory allocated to BL2 from 64KB to 128KB
- Show the layout of Code SRAM after image has been copied to the load
address
