  x86, kexec: Limit the crashkernel address appropriately

Keep the crash kernel address below 512 MiB for 32 bits and 896 MiB
for 64 bits.  For 32 bits, this retains compatibility with earlier
kernel releases, and makes it work even if the vmalloc= setting is
adjusted.

For 64 bits, we should be able to increase this substantially once a
hard-coded limit in kexec-tools is fixed.

Request that allocate_resource() use available space from high addresses
first, rather than the default of using low addresses first.

The most common place this makes a difference is when we move or assign
new PCI device resources.  Low addresses are generally scarce, so it's
better to use high addresses when possible.  This follows Windows practice
for PCI allocation.

The iomem_resource map reflects the available physical address space.
We statically initialize the end to -1, i.e., 0xffffffff_ffffffff, but
of course we can only use as much as the CPU can address.

This patch updates the end based on the CPU capabilities, so we don't
mistakenly allocate space that isn't usable, as we're likely to do when
allocating from the top-down.
