[POWERPC] More DCR native fixups
Getting BenH's new EMAC driver working on 440GP, I found some more problems in the native mode paths of the new DCR code: - dcr_map() is supposed to return a dcr_host_t, but the native version is a macro that doesn't expand to an expression. With native DCRs, dcr_host_t is an empty structure, so we just use a constructor expression instead. - dcr_unmap() uses {} instead of the safer do {} while (0) idiom to implement a no-op Here's a fix.
