Subject: [PATCH v5 09/13] 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.

-config KEXEC
- bool "Kexec system call"
- select KEXEC_CORE
- 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.

-config KEXEC_FILE
- bool "kexec file based system call"
- select KEXEC_CORE
- select KEXEC_ELF
- 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.
