The request_irq() needs to be done from ldc_alloc()
to avoid the following (caught by lockdep)

Many of the core sparc kernel files are not modules, but just
including module.h for exporting symbols. Now these files can
use the lighter footprint export.h for this role.

Semicolons are not necessary after switch/while/for/if braces
so remove them.

The sparc64 allmodconfig build broke due to enabling of the
branch_tracer that does some very clever things with
all if conditions. This caused my gcc 3.4.5 to be so confused that
it emitted a warning:
arch/sparc/kernel/viohs.c: In function `vio_control_pkt_engine':
arch/sparc/kernel/viohs.c:335: warning: 'nver' might be used uninitialized in this function
And with -Werror this broke the build.
Refactor code so it:
1) becomes more readable
2) no longer emit a warning with the branch_tracer enabled

o Move all files from sparc64/kernel/ to sparc/kernel
- rename as appropriate
o Update sparc/Makefile to the changes
o Update sparc/kernel/Makefile to include the sparc64 files
NOTE: This commit changes link order on sparc64!
Link order had to change for either of sparc32 and sparc64.
And assuming sparc64 see more testing than sparc32 change link
order on sparc64 where issues will be caught faster.
