Christoph Hellwig f1306f0423 riscv: only enable ZONE_DMA32 for 64-bit
Until we actually support > 32bit physical addresses for 32-bit using
highmem there is no point in enabling ZONE_DMA32.  And even if such
support is ever added it probably should be conditional to not burden
low end embedded devices.
