crypto: x86/chacha20 - satisfy stack validation 2.0
The new stack validator in objdump doesn't like directly assigning r11
to rsp, warning with something like:
warning: objtool: chacha20_4block_xor_ssse3()+0xa: unsupported stack pointer realignment
warning: objtool: chacha20_8block_xor_avx2()+0x6: unsupported stack pointer realignment
This fixes things up to use code similar to gcc's DRAP register, so that
objdump remains happy.
