Subject: [PATCH] riscv: enable HAVE_ARCH_HUGE_VMAP for XIP kernel
HAVE_ARCH_HUGE_VMAP also works on XIP kernel, so remove its dependency on
!XIP_KERNEL.
This also fixes a boot problem for XIP kernel introduced by the commit in
"Fixes:". This commit used huge page mapping for vmemmap, but huge page
vmap was not enabled for XIP kernel.
Fixes: ff172d4818ad ("riscv: Use hugepage mappings for vmemmap")
