parisc/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.

	help

	  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.



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

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

	  initially work for you.

	help

	  This enables the kexec_file_load() System call. This is

	  file based and takes file descriptors as system call argument

	  for kernel and initramfs as opposed to list of segments as

	  accepted by previous system call.
