Randy reported build errors in linux-next where XIP_KERNEL was enabled. ARCH_THEAD requires alternatives to support the non-standard ISA extensions used by the THEAD cores, which are mutually exclusive with XIP kernels. Clone the dependency list from the Allwinner entry, since Allwinner's D1 uses T-Head cores with the same non-standard extensions.

A fix for a randconfig issue Randy spotted in linux-next at the weekend. This fix has been in linux-next since Monday. Noticed your PRs hadn't gone out, so figured I should send this, rather than let the issue sneak into mainline.
