crypto: hisilicon/qm: Fix to enable build with RISC-V clang
With CONFIG_ACPI enabled for RISC-V, this driver gets enabled in
allmodconfig build. However, build fails with clang and below
error is seen.
drivers/crypto/hisilicon/qm.c:627:10: error: invalid output constraint '+Q' in asm
"+Q" (*((char __iomem *)fun_base))
^
This is expected error with clang due to the way it is designed.
To fix this issue, move arm64 assembly code under #if.
