ia64/kexec: refactor for kernel/Kconfig.kexec 

The kexec and crash kernel options are provided in the common
kernel/Kconfig.kexec. Utilize the common options and provide
the ARCH_SUPPORTS_ and ARCH_SELECTS_ entries to recreate the
equivalent set of KEXEC and CRASH options.

	  kexec is a system call that implements the ability to shutdown your

	  current kernel, and to start another kernel.  It is like a reboot

	  but it is independent of the system firmware.   And like a reboot

	  you can start any kernel with it, not just Linux.



	  The name comes from the similarity to the exec system call.



	  It is an ongoing process to be certain the hardware in a machine

	  is properly shutdown, so do not be surprised if this code does not

	  initially work for you.  As of this writing the exact hardware

	  interface is strongly in flux, so no good recommendation can be

	  made.
