Use extended crashkernel command line on i386
This patch removes the crashkernel parsing from
arch/i386/kernel/machine_kexec.c and calls the generic function, introduced in
the last patch, in setup_bootmem_allocator().
This is necessary because the amount of System RAM must be known in this
function now because of the new syntax.
