[U-Boot] [PATCH] armv8/spin_table.c: fix spin table release address

[Tsung-Han Lin]

Hi,

Sorry that I sent this patch twice and they are actually the same one.
I thought the first mail was failed because I got a message from the mail
server said that it is not sent to one of the maintainers.

Regards,
Tsung-Han

> Since only the master core will relocate itself, the spin-table release
> address seen by master core and other slave cores is different.
> This commit fixes this issue by recalculating the spin-table release
> address' offset instead of leaving it to compiler.
