Subject: power/fadump: make FA_DUMP select CRASH_DUMP
Date: Sun, 4 Feb 2024 11:06:54 +0800

FA_DUMP which is similar with kdump needs vmcoreinfo exporting,
crashkernel reservation and /proc/vmcore file . After refactoring crash
related codes and Kconfig items, make FA_DUMP select CRASH_DUMP. Now
the dependency layout is like below:

                           ---->VMCORE_INFO
                         /|
FA_DUMP--> CRASH_DUMP-->/-|---->CRASH_RESERVE
                        \ |
                          \---->PROC_VMCORE
