Add and use a generic version of devmem_is_allowed()
As part of adding STRICT_DEVMEM support to the RISC-V port, Zong provided an implementation of devmem_is_allowed() that's exactly the same as the version in a handful of other ports. Rather than duplicate code, I've put a generic version of this in lib/ and used it for the RISC-V port. * palmer/generic-devmem: arm64: Use the generic devmem_is_allowed() arm: Use the generic devmem_is_allowed() RISC-V: Use the new generic devmem_is_allowed() lib: Add a generic version of devmem_is_allowed()
