RISC-V: make ARCH_THEAD preclude XIP_KERNEL
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.
