Make dtstruct variable to be 8 byte aligned
[PATCH 1/2] Make dtstruct variable to be 8 byte aligned
kexec is creating a version 3 device tree to be backwards compatible. This
version of the struct has 8-byte alignment for properties whose value is 8 or
more bytes. As the code directly checks the pointer when deciding to add the
alignment word, the struct memory must start on an 8 byte boundary. Force the
dtstruct variable to be always 8 bytes aligned.
