  [Yakkety SRU] Enable KEXEC support in ARM64 kernel

Status in linux package in Ubuntu:
  In Progress

Bug description:
   * If the kernel is not built with CONFIG_KEXEC support, kexec-tools will not 
be able to live boot a new kernel over the running one.
   * Our partners/customers have requested this feature.

  [Test Case]
   * Install a version of kexec-tools that supports ARM64
   * Run the command: sudo kexec -l /boot/<kernel> --initrd=/boot/<initrd> 
--append="<append string>
   * You should see the message:  kexec_load failed: Function not implemented

  [Regression Potential]
   * The proposed config changes are limited to ARM64 architecture, overall 
risk of regression is low.
  [Other Info]
   * Please note that kexec-tools currently is not built for ARM64
   * I have an SRU to enable that bugs.launchpad.net/bugs/1659618
   * I am working with dannf to get kexec-tools to support ARM64 in yakkety.
