x86: Move find_smp_config() earlier and avoid bootmem usage
Move the find_smp_config() call to before bootmem is initialized.
Use reserve_early() instead of reserve_bootmem() in it.
This simplifies the code, we only need to call find_smp_config()
once and can remove the now unneeded reserve parameter from
x86_init_mpparse::find_smp_config.
We thus also reduce x86's dependency on bootmem allocations.
