We have many different pointer arrays which we put into linker sections
and each time there's one added we have to adjust all linker scripts.
This adds a common RO_DATA_SECTION define and uses it for all
architectures. This makes it easier to add a new linker array.

For the older section defines we specify the start and end addresses
outside the macro which means we have to repeat them in each linker
script. Make the start/end addresses part of the define to simplify
things. While at it, add a BAREBOX_ prefix to the INITCALLS and EXITCALLS
macros for consistency to the other defines.

The RATP implementation now allows executing generic commands with a
binary interface: binary requests are received and binary responses
are returned.

Each command can define its own RATP request contents (e.g. to specify
command-specific options) as well as its own RATP response contents
(if any data is to be returned).

Each command is associated with a pair of numeric unique request and
response IDs, and for easy reference these IDs are maintained in the
common ratp_bb header. Modules may override generic implemented
commands or include their own new ones (as long as the numeric IDs
introduced are unique).

Since patch e92abad36307d the linker discards sections which seems not
used to make the image smaller.
But this change will discard the whole init and exception code from start.S
which renders the final image useless.

From 'barebox.map' without this patch:

Discarded input sections
 .text          0x0000000000000000     0x358c arch/ppc/mach-mpc5xxx/start.o
 .data          0x0000000000000000        0x0 arch/ppc/mach-mpc5xxx/start.o
 .bss           0x0000000000000000        0x0 arch/ppc/mach-mpc5xxx/start.o
 .got2          0x0000000000000000       0x24 arch/ppc/mach-mpc5xxx/start.o
[...]

So, define the entry point to mark the init and exception used.

From 'barebox.map' with this patch applied:

Discarded input sections
 .data          0x0000000000000000        0x0 arch/ppc/mach-mpc5xxx/start.o
