This is a collection of misc cleanups I have accumulated when working on some
recent OpenRISC projects.

The patch themes:
 - Sparse warning cleanups
 - Removal of dead code
 - Emergency debug fixups in head.S
 - Support for gcc machine instruction flags
 - defconfig updates for litex

I have tested these patches when verifying the glibc port by running the glibc
test suite.

Changes since v1:
 - Fix if/elif issue in emergency print fixes pointed out by Samuel Holland
