Subject: parisc/kexec: refactor for kernel/Kconfig.kexec
Date: Wed, 12 Jul 2023 12:15:40 -0400

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.
