Josh Poimboeuf d3dfbfe2e6 crypto: x86/sha256-avx2 - Fix RBP usage
Using RBP as a temporary register breaks frame pointer convention and
breaks stack traces when unwinding from an interrupt in the crypto code.

There's no need to use RBP as a temporary register for the TBL value,
because it always stores the same value: the address of the K256 table.
Instead just reference the address of K256 directly.
