riscv: alternative only works on !XIP_KERNEL
commit c80ee64a8020ef1a6a92109798080786829b8994 upstream.
The alternative mechanism needs runtime code patching, it can't work
on XIP_KERNEL. And the errata workarounds are implemented via the
alternative mechanism. So add !XIP_KERNEL dependency for alternative
and erratas.
