zipl/boot: use C pre-processor for linker script generation

Browse Source 
Use C pre-processor for linker script generation and refactor some
constants. This allows the usage of the constants in our "linker
scripts" `*.lds.S` (actually, these are assembler files, so we can
make us of the C pre-processor and its capabilities).

While at it, enforce the described memory layout in the generated
linker script.
