arm64/crashdump-arm64: increase CRASH_MAX_MEMORY_RANGES to 32k

On ARM64 based VMs hotplugging more than 31GB of memory will cause
kdump to fail loading as it's hitting the CRASH_MAX_MEMORY_RANGES
limit which is currently 32 on ARM64 given that the  memory block size
is 1GB. This patch is raising CRASH_MAX_MEMORY_RANGES
to 32K similar to what we have on x86, this should allow
kdump to work until the VM has 32TB which should be
enough for a long time.
