RISC-V: Fix some RV32 bugs and build failures
This patch set fixes up various failures in the RV32I port. The fixes are all nominally independent, but are really only testable together because the RV32I port fails to build without all of them. The patch set includes: * The removal of tishift on RV32I targets, as 128-bit integers are not supported by the toolchain. * The removal of swiotlb from RV32I targets, since all physical addresses can be mapped by all hardware on all existing RV32I targets. * The addition of ummodi3 and udivmoddi4 from an old version of GCC that was licensed under GPLv2 as generic code, along with their use on RV32I targets. * A fix to our page alignment logic within ioremap for RV32I targets.
