Coiby Xu e3a84be1ec arm64,ppc64le/kdump: pass dm-crypt keys to kdump kernel 
CONFIG_CRASH_DM_CRYPT has been introduced to support LUKS-encrypted
device dump target by addressing two challenges [1],
 - Kdump kernel may not be able to decrypt the LUKS partition. For some
   machines, a system administrator may not have a chance to enter the
   password to decrypt the device in kdump initramfs after the 1st kernel
   crashes

 - LUKS2 by default use the memory-hard Argon2 key derivation function
   which is quite memory-consuming compared to the limited memory reserved
   for kdump.

To also enable this feature for ARM64 and PowerPC, the missing piece is to
let the kdump kernel know where to find the dm-crypt keys which are
randomly stored in memory reserved for kdump.  Introduce a new device tree
property dmcryptkeys [2] as similar to elfcorehdr to pass the memory
address of the stored info of dm-crypt keys to the kdump kernel.  Since
this property is only needed by the kdump kernel, it won't be exposed to
userspace.
