[PATCH v2 2/3] riscv: make header self-contained

[Ahmad Fatoum]

From: Ahmad Fatoum <a.fatoum at barebox.org>

In preparation for adding a call to sync_caches_for_execution() into
common code, make sure inclusion of asm/cache.h on RISC-V doesn't
require any extra headers to be included beforehand.
