Use extended crashkernel command line on sh

This patch removes the crashkernel parsing from arch/sh/kernel/machine_kexec.c
and calls the generic function, introduced in the generic 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.
