[coreboot] rm elfboot and ELF from v3 (not lar)

This is another attempt at removing ELF support from v3.  I'll try to
do a better job of explaining and justifying this time.  The patch
should be followed by:
svn rm include/elf_boot.h
svn rm include/elf.h
svn rm include/arch/x86/arch/elf.h
svn rm lib/elfboot.c
svn rm arch/x86/archelfboot.c

Another follow-on would be to fix lar so it never puts an ELF into the
lar without parsing it.

Here are my reasons:
1. It wasn't being used anyway.
           Unless you used lar to load the elf in, the Makefile always
parsed the elf with -e
2. It duplicated code.
           There is no reason for v3 to understand ELF when lar parses it.
3. It saves space.

Here's the last little bit of stage0.init.map

Without the patch:

ffffcc8c T rawpnp_write_config
ffffcca8 T rawpnp_set_logical_device
ffffcccb T rawpnp_set_iobase
ffffccf4 T rawpnp_set_enable
ffffcd19 T rawpnp_enter_ext_func_mode
ffffcd20 T rawpnp_exit_ext_func_mode
ffffd51f t __FUNCTION__.1410
ffffd540 t console_test.1503
ffffd57b T _estage0_1
fffffff0 A _ROMTOP
fffffff0 T _resetjump

With the patch:

ffffc885 T rawpnp_enter_ext_func_mode
ffffc88c T rawpnp_exit_ext_func_mode
ffffce20 t console_test.1503
ffffce5b T _estage0_1
fffffff0 A _ROMTOP
fffffff0 T _resetjump

I'm calculating the difference by subtracting the locations of _estage0_1
fffd57b - fffce5b = 0x720 = 1824 bytes

Not earth-shattering, but significant.
