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

-         but it is independent of the system firmware.   And like a reboot
-         you can start any kernel with it, not just Linux.
